Right front wheel pull to the right when i step on the brake why?

probably none of the above
have the brake master cylinder replaced first
then work on the pins that allow the calliper body to self center
probably seized on the pins holding one pad on the rotor

I think you could use this manual method instead.. My
nephew use it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com

Front brake
Step 1: Identify Front Disc Brake Components

Front Wheel Drive Brake Assembly
Most front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits, road conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace Pads

Removing Brake Caliper Mounting Bolts
Locate primary caliper mounting bolts; apply wrench pressure counter-clockwise (When looking at the head of the bolt) to remove the bolts, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.
Step 3: Remove Front Brake Caliper

Remove Front Brake Caliper
After removing the primary caliper mounting bolts lift the brake caliper off of the rotor and then tie or secure to the side, being careful not to bend or kink the brake caliper flex hose. Thoroughly inspect brake caliper and brake hoses for leakage, cracks or chaffing and replace as needed. Next remove the brake pads (If not mounted in the caliper) and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.
Step 4: Remove Brake Pads

Remove Front Brake Pads
Once the brake pads have been removed, make sure if there is anti rattle hardware to transfer to the new brake pads. Some brake pad manufacturers will include the proper lube (Caliper slides) and anti-rattle hardware to ensure proper performance of their product.
Step 5: Remove Caliper Mount

Remove Caliper Mount Bracket
Finish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad friction surfaces of all foreign material or build-up.
Step 6: Remove Brake Rotor

Remove Brake Rotor
With the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use penetrating oil to free it up. Some manufacturers use small screws to hold the rotor on as well. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.
Step 7: Depressing the Brake Caliper

Resetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid or open the brake caliper bleeder screw to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston. Close the bleeders once the piston is retracted completely
Step 8: Installing New Brake Rotor

Install Brake Rotor
Install new brake rotor, the new rotor is manufactured with a protective film over the rotor to keep it from rusting, remove protective film with brake cleaner before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake Pads

Installing New Brake Pads
Reinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are seated properly in the caliper mount; it must be a close fit to work properly..
Step 10: Reinstall Front Brake Caliper

Re-Install front Bake Caliper
Reinstall front brake caliper and reinstall caliper-mounting bolts, recheck all mounts and mounting bolts. Check the caliper slides to be sure there is no bind and that the caliper moves freely back and forth on the caliper slides. Bleed brake system per manufacturer's specifications to relieve any air trapped in the system. Before driving the vehicle, push the brake pedal down and let it up slowly, repeat until normal brake pedal operation resumes, this operation is forcing the brake pads to travel to the brake rotors.

How to Replace Front Rotors on a Mazda6
1. Step 1 Park the Mazda6 on a flat paved surface. Apply the parking brake and release the hood latch. Place a wheel chock behind one of the rear tires and open the hood. **** out half the fluid from the master cylinder reservoir using the turkey baster and discard. Replace the master cylinder cap securely.
   
2. Step 2 Break the lug nuts loose on the front tire, using the breaking bar and a 21-mm socket. Raise the left quarter panel first with the floor jack and place the jack stand under the left front frame rail. You can lift the right side too or just do one side at a time. Remove the lug nuts and the wheel when elevated.
   
3. Step 3 Pry the two plastic caliper slide bolt covers off with the flathead screwdriver and remove the caliper slide bolts with the ratchet and a socket. Pry the caliper off the pads and rotor with the screwdriver and support it to the coil spring with the bungee cord so it does not dangle by the brake hose. Compress the piston of the caliper inward using the C-clamp until the piston bottoms out in the caliper casing.
   
4. Step 4 Remove the pads from the caliper anchor by prying them out gently with the screwdriver. Be sure to memorize how they were positioned in the anchor so you can replace them the same way in the event you're not replacing the pads as well. Remove the caliper anchor bolts using the ratchet and a socket. They're going to be extremely tight, so be prepared. Remove the caliper anchor.
   
5. Step 5 Locate the retaining screw on the hub face of the rotor. Use the impact screwdriver in the reverse position with a Phillips head bit and strike the end of the screwdriver with the hammer. Remove the screw. Remove the rotor. If it is stubbornly stuck to the hub, strike it a few times with force on the plated fins of the rotor.
   
6. Step 6 Spray the new rotor with brake clean and be generous to clean off the oil coating that new rotors have on them so they will not rust from condensation in the air while they were in storage. Clean both sides and wipe dry with a shop rag. Place the new rotor on the hub and make sure to line up the retaining screw hole in the rotor to the hub. Replace and tighten the retaining screw.
   
7. Step 7 Replace the caliper anchor and bolts and tighten tightly. Replace the pads into the caliper anchor in the same manner you removed them. Replace the caliper over the pads and rotor and replace and tighten the caliper slide bolts. Replace the plastic covers.
   
8. Step 8 Replace the wheel and lug nuts and tighten the lug nuts so they are flush. Lower the Mazda6 and torque the lug nuts alternately with the torque wrench, set at 80 foot-pounds and the 21-mm socket. If you raised both sides of the front axle, wait until you've replaced the right side rotor, otherwise repeat Step 2 through Step 8 for the right side.
   
9. Step 9 Pump the foot brake pedal until it feels normal to restore the hydraulic pressure back to the compressed caliper pistons. Release the parking brake.
   
10. Step 10 Check and add new DOT 3 brake fluid to the master cylinder and replace the cap securely. Close the hood. Remove the wheel chock and test drive
    

How to Replace Brake Pads
(DIY Complexity: Moderate - Time: 2.8 hours)

Parts:
1. Brake Pad Set

Tools:
1. C-Clamp
2. Flat Head Screwdriver
3. Jack Stand Set
4. 3/8 in. Drive Ratchet
5. Combination Wrench Set
6. Tire Iron
7. Socket Set
8. 1/4 in. Drive Torque Wrench
9. Dial Indicator

Supplies:
1. Brake Cleaner
2. Brake Lubricant

Steps:
Step 1 Secure your vehicle on a level surface, making sure your car will not roll or lean too much when jacked up.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 Remove the cap from the brake master cylinder. Using a turkey baster, remove a quarter of the brake fluid from the master cylinder. Lift up the front of your vehicle using a floor jack.
o Tip: Using an aftermarket floor jack, instead of the original equipment (OE) jack, can make the job easier and safer. Verify the condition of the floor jack before use.

Step 3 Secure the vehicle with jack stands on both sides for safety before starting any work. The pinch welds and the frame are the two best locations. Do not rely on the jack to hold the vehicle up while working.
o Tip: Try to find a flat, level, and strong surface to put the jack stands.

Step 4 Remove the front wheels by removing the lugs nuts that are holding them on. To do this you will need to find the correct size socket and large ratchet or tire iron and turn them counter clockwise. If your vehicle is equipped with hub caps (plastic covers over the wheels), these will need to be removed to access the lug nuts.
o Tip: It is a good idea to try and break the lug nuts free before you jack the wheels off the ground. This way they you will not spin the front wheels or put stress on the transaxle.
o Tip: Lug nuts fasten the wheel to the hub and may be on very tight. To gain more leverage, use a breaker bar to loosen the nuts.

Step 5 Inspect the brake rotors for scoring, grooves, cracks and discoloration.

Step 6 Remove the brake caliper mounting bolts.

Step 7 Slide the brake caliper off of the brake rotor.
o Tip: If the brake rotors are worn and there is a big lip preventing the brake caliper from sliding off easily, gently pry one pad back into the brake caliper to clear the lip and make removal easier.

Step 8 Support the brake caliper up and away from the working area. Make sure you do not kink or pinch any brake lines. Do not disconnect the brake line.
o Tip: Use a bungee cord to secure the brake caliper out of the way and hang it on the suspension spring.

Step 9 Remove the brake pads from brake caliper.

Step 10 Compress caliper piston using a C-clamp.

Step 11 Install the new brake pads in the brake caliper.

Step 12 Reinstall the brake caliper.

Step 13 Torque the brake caliper mounting bolts to manufacturer’s specifications. Repeat for other side.

Step 14 Install wheels and torque to manufacturer’s specifications.

Step 15 Refill the brake fluid in the brake master cylinder and reinstall the cap.

Step 16 Road test vehicle, break in new pads.
o Tip: To break in pads and rotors refer to manufacturers recommendations. Some companies have different procedures for pad and rotor break in.


Hope this helped (remember comment and rated this).

Jack-up the car on the side to be dealt with first, and secure it with jackstands or something that will hold the car up and secure. after this remove the wheel. The caliper has TWO retaining bolts accessed from the back of the caliper. these have to be removed. after this you will be able to pull the cliper off of the disc. Remove the old pads NOTE POSITION OF ANY CLIPS THAT ARE PRESENT for replacement after new pads are installed. If the plunger is too far out to replace the pads and fit over the disc, use a large pair of channel-lock pliers to compress the plunger back in to the caliper. It may be necessary to release the bleeder on the caliper to allow the comperssion of the plundger. 1/2 turn usually is sufficient. replace the pads and reverse the order of steps. repaet on all four, or just front. DO NOT replace just one pad as stopping will cause a sharp turn to the side replaced when stopping.

Hope this help (remember rated and comment this).

1. Step 1 Remove ½ of the brake fluid from the master cylinder with the syringe and replace the cover. Discard the fluid.
   
2. Step 2
3. Remove the front hubcaps and loosen the wheel nuts using the lug wrench, but do not remove the nuts.
   
4. Step 3 Lift the front end of the LeSabre with the floor jack and secure safely onto the jack stands.
   
5. Step 4 Remove the wheel nuts and wheels. Screw one wheel nut back onto a wheel stud hand tight to retain the rotor away from the caliper assembly.
   
6. Step 5 Place a large C-clamp over the left inboard caliper housing and the outboard pad, and tighten to compress the caliper piston.
   
7. Step 6 Remove the two caliper guide bolts using a box end wrench. Remove the caliper and secure it to the vehicle chassis with mechanic's wire or a metal hook.
   
8. Step 7 Remove the outboard pad from the caliper on the LeSabre first. Pry it off the outboard caliper housing using the screwdriver.
   
9. Step 8 Remove the inboard pad by lifting the retaining clips out of the caliper bore.
   
10. Step 9 Clean the surface of the caliper bridge that contacts the backing plate of the pads using a wire brush, and apply a thin coat of brake lubricant to the contact points. Be careful not to let the lubricant get onto the rotor.
    
11. Step 10 Install the new inboard brake pad and shim into the caliper piston bore by pressing the retaining clips into the bore until it locks into place.
    
12. Step 11 Install the outboard pad onto the caliper housing, making sure to align the retaining clips into the holes in the caliper. Use the screwdriver to convince the clips onto the caliper if necessary.
    
13. Step 12 Replace the caliper over the rotor.
    
14. Step 13 Clean off the surface of the guide bolts and apply a light coat of lubricant to the smooth surface of them. Align them properly through the rubber boots and bolt the caliper to the knuckle. Tighten the guide bolts using the wrench. Remove the wheel nut from the wheel stud securing the rotor.
    
15. Step 14 Replace the wheel and wheel nuts. Tighten the wheel nuts snugly, and re-tighten them (with a torque wrench is recommended set at 100 foot pounds) once the LeSabre is back on the ground.
    
16. Step 15 Repeat steps 5 through 14 for the right side.
    
17. Step 16 Pump the brake pedal when you're through to seat the new pads against the rotors, then check and add new brake fluid to the master cylinder.
    

The hard part is pressing the caliper piston abck into the caliper so you can get the new, thicker pads over the rotor. A large C Clamp works best.

pull the wheels off .undo brake fluid cover .On the back of rotor there are 2 long pins that you have to remove to pull the caliper off.After the caliper is off pull the old brake pads off ,remembering which way they came off.Now with either a large C-Clamp ,or large channell lock pliers compress the large round metal part that pushes against the back of brake pad.The idea is this,your new pads wont fit on the rotor unless you compress this part ALL the way down,that is why you took the fluid cover off earlier,so the back pressure can go back into the brake fluid reservoir .Once you have this part pushed in ,install the 2 pads and put the whole thing back over and on the rotor .Last of all put the long pins back on tight, put the wheel on ,and now do the other side.............Good luck ! Patience is Key !!
