Open the bleeder on the brake caliper, if you can then retract the piston then replace the brake hose that aitches to the caliper if after you open the bleeder you still can not retract the caliper piston then you will need to replace the caliper.....GOOD LUCK

How to replace front brake pads?


For most cars it is very simple process, pull wheel, look for caliper bolts, usually two, loosen, remove, wiggle caliber to pull out and away from rotor, remove pad clips to release, slide out pads, noting position so you install new ones the same way, inside pad and outside pad, apply pressure to spread pads apart to fit on rotor, some pistons will remain open, some will close a bit and rotor will not fit, so applying pressure to retract pistons is usually required, I use flat prybar using two putty knife blades not to damage pads, once you have pads retracted, act fast and slide over rotor and position and insert bolts, pay attention to torque specifications on bolts for calipers. You can usually find videos on YouTube which help if needed. Good luck. FREE-VSTREAMTV.com

Got new brakes and rotors & after 30-40 mi. of driving it stinks bad and by home, it was smoking. Help


One or both of the brake callpers are not releasing when you release pressure on the brake pedal so you have continued contact between the brake pads and the brake rotor. This will overheat the brake pads and rotors and produce a burning smell and smoke.

If your brakes were working fine before the people you used to fit the new pads and rotors got hold of your car then the most likely cause will be faulty installation. For example if the inner and outer brake pads have been reversed when fitted in the brake caliper this will cause your brakes to bind up as you have described. If the brake caliper slides have not been properly lubricated with the correct product (or not lubricated at all) the calipers can bind up and hold the pads on the brake rotor.

In your case I would suspect the new brake pads have probably been reversed during installation and that is what I would be looking at first. But there are other possibilities that may also need to be checked.

You can take the vehicle back to whoever did the sloppy work and get them to fix it or take it to a competent mechanic very close to home who can check over the installation work. (Those that did the work should have road tested the car before giving it back to you and binding brakes should have been noticed if they were half competent). You don't want to be driving far when your brakes are like this.

2. Your brakes can also bind up as you have described if there is a blockage in one or both of the flexible brake hoses connected to the brake caliper. Usually you won't get two at once though. When this happens the blockage in the line will not allow the brake fluid to flow back up the lines when you release the brakes (and there is no pressure pushing it back) so the brake pads will not release from the brake rotor. The flexible brake lines need to be replaced every 7 -8 years or so as they deteriorate badly from the inside but outside they may look just fine. If one or more of your flexible brake lines were bad before you replaced the brake pads and rotors then fitting the new pads and rotors will really show up the problem.

3. You can also have a brake binding problem if the piston in one or more of your brake calipers is corroded and will not retract back into the bore when brake pressure is released. The piston or pistons in the calipers press on the back of the brake pad unit and force the pad onto the brake rotor. If the pistons are corroded (which will often be the case in old calipers) they can bind up in the caliper bore and not retract back into the bore when the brake pressure is released. If you had this problem before the new pads and rotors were fitted the problem will show up much more now that new pads have been fitted. It is a simple task to check if any of the pistons in any of the brake calipers in your car are binding up and not retracting as it is any of the installation work that has been done.

Some businesses will do very sloppy brake work and not check that everything is freely moving correctly when the brake pedal is applied and released as you need to when replacing brake pads.

Brakes wont bleed out even after new master cylinder, calipers, rotors and pad


undo the lines at the master cylinder and place your fingers over the holes to act as one way valves . Have a friend gently pump the brakes and release any air in the cylinder. Replace the lines and start at the longest line working back to the shortest. IF that dosen't work you may have to pressure bleed the system. It is not normal to prime a new master cylinder but I make it a practice using a rod I pump the m/cyl before fitting it in the car. It saves a lot of heart ache.

Replacing the rear pads & rotors but the calipers won't release from the old rotor.


You probably have the pistons in the calpierts jammed by corrosion build up from when you pushed the piston back in to fit the new pads. When you put your foot on the brakes this corrosion has jammed the piston in the full out position and as there is no return spring action on calpiers the pads stay jammed in the on position. Only fix is to replace calpiers or have new pistons and seals fitted.

How can I change the rotors and brakes on a 2006 Cadillac?


Front brake
Step 1: Identify Front Disc Brake Components
brake_pads_rotor.jpg
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
brake_pad_set.jpg
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_brake_caliper.jpg
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_brake_pads.jpg
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_brake_pads_holder.jpg
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
brake_rotor.jpg
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
compress_caliper.jpg
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
new_brake_rotor.jpg
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
new_brake_pads.jpg
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
front_brake_rotor_pads.jpg
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.

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

Front Rotoe removal 1990 Toyota 3Runner


Take off the disk pad, release the pressure.
1. Loss the brake fluid small fitting on the cylinder, then use one hand slowly loss the fitting and use another hand with flat screw driver pressure the brake pad toward the piston of the cylinder AT THE SAME TIME , as soon as you release the pad a little bit, close the fitting right away, DO NOT LET THE AIR GET INTO YOUR BRAKE LINE. After you release the pad, TIGHT the fitting.

2. Take off two screws behind the cylinder which connected to the body and remove the cylinder first and then take off the rotor.

3. When you put back, don’t touch the fitting, after you finish it, check everything is O.K. then start the car, pump the brake several times, until you feel the brake is normal.


For your safety, use emergency brake and also put something behind your rear wheel to completely stable the car.

Good luck, hope this can help you.
