Hi to get the pads in you did screw the calipers pistons all the way back and you should have backed the hand brake cable off as well then adjusted the cable afterwards problem with self adjusting calipers is you can adjust the handbrake cable and the brakes are ok until driven then they can bind so try backing the adjustment off on the handbrake [should really change both calipers as a pair to keep the axles brake balance but this is not anything to do with the brakes binding] best of luck paul

Overheating brakes


I think the problem is the brake pad or caliper, brake pad are too thick or the caliper are not good casted.
First try to confirm if you get a right brake caliper ,then confirm the brake disc ,brake pad, if they all ok, tear down the bracket of caliper, put into brake pad, then put into brake rotor.

I replaced the rear pads and rotors.I screwed the pistons all the way in to get the pads on. Now I have a soft pedal and was told I needed to adjust the piston back out a little bit but I cant figure how...


soft pedal usually indicates air in the system. when you put it all back together and applied the brakes did you check to see if the brake fluid in the master cylinder was topped up with brake fluid ?. it would appear that the system needs to be bled. check for leaks as well and it is possible you may have damaged the pistons in the calipers when you pushed them in to make room for the pads.

Change rear brake discs


  1. here is some instuctions on how to do the brake pad replacement this should help you out
  2. Jack up the vehicle on a secure metal part of the vehicle and place jack stands in the same area.
  3. 2 Lower the jack until the weight of the car is solely on the jack stands.
  4. 3 Loosen the lug nuts and remove the wheel from the vehicle, exposing the brake system.
  5. 4 Loosen the caliper slide pins from the rear of the caliper and slide the caliper pins out of the caliper.
  6. 5 Remove the caliper from the brake system and remove the old brake pads.
  7. 6 Secure the caliper to a part of the suspension with a bungee cord to avoid it hanging by the rubber brake hos, where it could be damaged or start leaking.
  8. 7 Loosen the two bolts that hold the caliper bracket to the vehicle and remove the caliper bracket.
  9. 8 Pull the rotor from the vehicle.
  10. 9 Measure the thickness of the rotor with the micrometer. Compare the measurement to the "minimum thickness" stamp on the rotor or the manufacturer specifications in the repair manual.
  11. 10 Take the rotors to a machine shop to have them resurfaced if they are above specification and need resurfacing. Verify the manufacturer's recommendations in the repair manual, as rotors do not always need to be resurfaced or replaced.
  12. 11 Reinstall the rotor on the vehicle.
  13. 12 Place the caliper bracket back on the vehicle and hand tighten the bolts on the back of it.
  14. 13 Torque the bracket bolts down to the manufacturer specifications in the repair manual.
  15. 14 Place a new hardware kit in the caliper bracket and set the pads in the hardware.
  16. 15 Press in the caliper piston with the caliper piston tool to allow the caliper to fit over the new brake pads.
  17. 16 Slide the caliper over the brake pads and reinstall the caliper slide pins.
  18. 17 Torque the caliper slide pins to the manufacturer's specifications.
  19. 18 Replace the wheel on the vehicle and torque it down to manufacturer specifications located in your repair manual.
  20. 19 Lift the vehicle off of the jack stand with the floor jack and remove the jack stands.
  21. 20 Lower the vehicle to the ground and remove the floor jack.
  22. 21 Press the brake pedal several times to pressurize the brake system before test driving the vehicle.
  23. 22 Drive the vehicle, performing several hard stops to make certain the brakes are operating properly.

Remove rear brakes from 2006 jeep grand cherokee laredo


its very easy. Pull tires off after putting vehicle on jack stands. There are only 2 bolts that holt the caliper on the rotor. Once you remove those bolts, the caliper will slide off. the break pad removal can be a little tricky, as you must depress a button with a screw driver in order to get he pads out. I recommend having two people to do this part. Once the old pads are out, us either a c-clamp or a pair of chanel locks to push the piston back in. Once the piston is back in, insert the new pads, place the caliper back on the rotor and reinsert the two bolts. I dont know the specs of the bolts, but be sure not to tighten them too much as you can damage parts to the brake system. It literally took me 20 minutes to do my brakes.

I need to put pads and rotors on lumina i need a refresher to takeing pads and rotors


Pads and rotors are easy. You will have to take the tire off. There will be two bolts on the back side of the calipers. You will need a large allen wrench to remove them. Once you get the calipers loose, you can swap out the pads. The rotors will slid off the axle itself without having to take anything else loose. When you put the calipers back in place, tighten the bolts you removed. After you get everything put back together, make sure you pump your brakes till they get tight BEFORE and AFTER you start your vehicle. You need to test your brakes out before you drive off. The bolts are self tightening.

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.

Brake pedal goes to the floor only when engine is running. Pedal is perfect with engine off.


your power brake booster is blown out
the seal has a leak in it
run the truck for 3 minutes and shut it off. with the windows up listen carefully while you gently apply the brakes
listen for a hissing sound of air leaking.
the sound of these leaking is a very soft sound
