Replace rear brake discs and pads


Depending on vehicle. Find level ground and park there. Put chocks in front and behind wheels not being lifted. Loosen lugs, jack up vehicle, set jack stands, lower vehicle on jack stands, remove lugs and wheel. Open hood remove brake fluid cap. Remove two bolts holding caliper, pull caliper off rotor disc and bracket, remove pads, place a used pad in front of caliper piston, use a c clamp to push caliper piston in caliper, remove c clamp and old pad, hang caliper up, remove 2 bolts holding caliper bracket, remove bracket, remove rotor, install new rotor, install caliper bracket, install new pads, install caliper, repeat this on other side, put cap back on brake fluid tank, remove bleeder fittings and keep pressing brake pedal until an even flow of brake fluid sprays out.

Should the center spindle nut and 2 torgued phillip head screws be removed to replace front brake rotor on 1999 honda accord lx


will try to help. 1st remove the wheel, then remove the 2 caliper bolts that hold the brake caliper on. after removal of brake caliper, [it should just pull off after the 2 bolts are removed] replace the brake pads[be sure to apply anti squeal lube to the outer side of the pads..not the pad itself,the one not contacting the brake rotor] install the pads, the you will need a C clamp to push the brake caliper pistons back into the caliper. i've used this installation easily. use the old pad ,place it against the caliper piston,then apply the C clamp and push the caliper piston back into the brake caliper, then the brake caliper will slide back over the new pads easily, no need to bleed the brakes if you use this solution. replace the brake caliper bolts, then go to next side and repeat the process. after the replacement of the front brake pads,pump the brakes with engine running!!! it's really a simple process. be sure the brake pads are facing the brake rotors with the [pads] facicing the rotors. no metal facing metal. easy! if you have added brake fluid recently, do not be alarmed if you see fluid coming out of the brake master cylinder,when you use the C clamp to collaspe the brake caliper back into the recessed position. [as always when you have to add brake fluid to the brake master cylinder,it only means your brakes are wearing naturally. if you have a vibration in front wheels or steering wheel when braking, you have a brake rotor or both front brake rotors that need replacement with your brakes also. hope this helps and as always, please get a second opinion if you have doubt. an expert will be happy to help. thank you for choosing fixya.com

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.

Front brakes installation


1) Block rear wheels and place Park brake ON
2) Jack up front end and use Jack Stands. If you dont have Jack Stands, you can use the Car Jack but when you remove the tire, slide the tire under the vehicle so that if it does fall off of the jack, it will land on the tire/rim and not your body. Always remember NEVER get any part of your body under the vehicle when it is not on Jack Stands.!!!!!
-- You can do 1 side at a time - Procedure is the same for Both Sides
3) Remove Tire
4) There are 2 bolts behind the brake caliper (the thing that holds the brake pads on.) You may need a special tool, it's kind of like an Allen Wrench, but it is sort of Star-Shaped, You can get these at any Car Parts Store. These bolts are inside 2 rubber tubes, don't remove these rubber tubes (like I did)....
5) Once you remove the 2 bolts, the caliper and shoes may then be lifted from the Brake Rotor.
-- Note: Once you remove the caliper, the brake rotor will come off. It is highly recommended that you take these brake rotors to a shop and have them 'turned'. If you don't, then your brake repair will result in faster wear of the new pads and may cause unbalanced braking. I know... I did the same thing trying to save money.
-- Or you can get new rotors and install them. They are not that much and new rotors will last longer than turned ones.
6) Remove the outer pad (Use a screw-driver to pry off the spring-holder.
7) To remove the inner pad, you should loosen the "Brake Bleed Valve" on the caliper and push the inner pad in *Pushing the piston in* This will make brake fluid come out of the bleed valve, so catch it in a pan. Once it's pushed in most of the way, Close the bleed-valve and then pry off the inner pad. If you DONT close the brake bleed valve and you try and pull the inner pad off, it will just **** AIR into the brake system, which sucks making step 16 that much harder...
8) Inspect the inner piston for rust / debrit. If there is damage to the piston, or you see brake fluid leakage anywhere on the caliper, you may have to get a new caliper.
9) Install the new inner pad by pressing it into the piston-Cup. You have to make sure you line up the pad also...
10) Install the new Outer Pad, Make sure that the locking clip Locks onto the caliper.
10a) This may be a good time to inspect your Axle and Wheel Bearings. If the Rubber is torn or missing from your axle (CV-Boot) that should be repaired.
11) Place the rotor back on the axle
12) Slip on the Caliper back over the rotor and make sure it is lined up properly to the caliper mount.
13) It is recommended to get NEW bolts, but if you dont, then re--install the bolts. Make sure they are tight.
14) Replace wheel.
15) Do the OTHER side.
16) Now that BOTH sides are done, you must now Bleed the Brake System.
-- You will need someone to sit inside the vehicle while you bleed the brakes.
a) Without the brake being pressed, make sure the Brake Fluid is topped filled to the Full Line.
b) Start the car
c) Start at the Right Rear of the vehicle
d) Tell the person to apply AND HOLD the brake pedal. Open the Bleed Valve and let air/fluid out. The driver should NOT let up on the pedal, but let it go to the floor and hold it there. Close the valve. Tell the driver to Pump and then HOLD the brake. Open the valve again letting air/fluid out. Driver should let the brake pedal go to the floor and hold, NEVER let up. Close the valve. You can repeat this process a few times until you hear NO air coming out.
d) Check the Brake Fluid Level make sure it's to the full line.
e) Move to the Left Rear Wheel and repeat step (d) for the Left Rear brake
f) Move to the Right Front and repeat step (d)
g) Move to the Left Front and repeat step (d).
17) Your brakes should now be bled. Make sure that the brake pedal does not feel "Mushy" but should feel "Firm". If it feels "Mushy", then you still have some air trapped in the brake lines and you need to bleed the brake system again.

I hope that this helps someone out there wanting to do their own brakes. This is not a End-All and All-Knowing procedure. I may also be missing some important things/steps that you must take. I am just sharing my experience in my doing my own brakes.

Install new brake pads and rotors all 4 wheels. Replaced front 2 calipers. Bled brakes. New clean fluid coming out. pedal is still soft and goes to floor. 200 Seebring.


Are you losing any Brake Fluid? Is it visible anywhere at the four wheels? Is it visible anywhere else?
The Master Cylinder may be defective. When you bled the Brakes did you maintain proper Brake Fluid Level in the Master Cylinder? If you didn't: and air entered into the Master Cylinder there maybe air within in the system in the Master Cylinder. You can bleed the Master Cylinder by removing the brake lines, adding more fluid, pumping the brakes, bleeding the air out of the system.
Are you losing Brake Fluid and can't find a noticeable leak? Then there is a good posibility that the rear seal in the Master Cylinder is leaking and the Fluid is going into the Brake Booster - which is the large wheel shaped drum located on the fire wall. In this case both the Brake Booster and the Master Cylinder will have to be removed and replaced. The Booster contains seals that Brake Fluid is very caustic to and will ruin these seals- causing future failures.
If no Brake Fluid is lost, no leak found: Check the Brake Booster Vacuum Advance. This should be connected to the outside of the Booster, attached to a hose, with the hose going to the engine. Check to see if this is working properly. Replace if needed.

Front brake drags at times overheats Replaced pads, caliper, bled brakes. still drags, overheats after a few miles. smoking..


Try replacing the brake hoses. With age they can partially collapse and not allow the fluid to flow properly, causing the caliper to stay extended.
Try a power bleed on the system, flush and replace your brake fluid.

Brakes


All you have to do is take the calipers off crack open the bleeder of the side you are working on leave the old pad in the caliper and press the pad in as far as it will go tighten bleeder clean the rotors with brake clean to get the oily substance off they put on during shipping to keep them from rusting put rotor back in place and put new pads in caliper if they give you grease for the caliper sliders put some on the caliper bolts and sliders the thing the bolts go into on the caliper so they move fairly easy this way your brakes will work better and last longer put caliper back in place tighten caliper bolts snug usually with a ratchet like a good 3/8 ratchet then do the other side fill up the master cylinder with proper brake fluid usually dot3 but should say on master cylinder cap bleed brakes if you did just the front bleed the passenger side first pump pedal a few times dont go all the way to the floor have someone open the bleeder on the right front passenger front while holding pedal down with just a little pressure one foot on pedal one under pedal so it dont go to the floor then do the same for the other side check fluid start vehicle if pedal is good go for a test drive and thats it.
