    My brakes lock up for no reason, I'm driving with the brakes applied without me pressing on them.

  • mpdipreta Mar 02, 2009

    Might be same issue, I'm driving along all the sudden the brakes feel like they are applied but I'm not touching them. Car stars to shake, smoke then brakes realease and ok.

    Left rear caliper piston stays lock. Will not retract and therefore the left rear brake overheat. When I check the left rear rotor temperature with infra-red sensor pyrometer after just driving 8 miles, the rotor temperature registered >500 deg. F. All the others are below 200 deg. F.

    This piston will retract if the valve bleeder is opened.

Squealing at the right front wheel


The brake lining's have worn away, the squealing was metal to metal (worn pad against metal disc) The worn pad will have damaged the brake disc. Very dangerous. You will now have to have new brake pads and discs fitted to BOTH front wheels to put it right. Good luck

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.

Vibration in rear of vehicle when braks are applied


I believe that the rear discs are warped or the tires are out of round when braking. More likely, the discs. --- The following are the instructions for replacing the front and rear pads for the front/back rotors. 1999-01 Grand Cherokee Front
  1. Drain 2?3 of the brake fluid from the front reservoir. Use the bleeder screw at the front outlet port to drain the fluid. If equipped with anti-lock brakes, relieve the system pressure.
  2. Raise and safely support the vehicle.
  3. Remove the wheels.
  4. Insert a small prybar through the caliper opening and pry the caliper (using the outboard brake pad) to bottom the pistons in the caliper bore. NOTE: This will back the brake pads off of the rotor surface to facilitate the removal and installation of the caliper assembly.
  5. Pry the caliper support spring out of the caliper.
  6. Remove both caliper slide pin bushing caps and slide pins.
  7. Lift the caliper from the anchor.
  8. Using a piece of mechanics wire, support the caliper so there is not tension on the brake hose.
  9. Remove the brake pads from the caliper. Fig. 2: Installing the inward brake pad on the front caliper pistons - 1999-01 Grand Cherokee 93026g92.gif
    To install:
  10. Position the brake pads onto the caliper.
  11. Position the caliper into place on the anchor.
  12. Coat the caliper slide pins with silicone grease and torque them to 21-30 ft. lbs. (29-41 Nm). Install the slide pin bushing caps.
  13. Install the caliper support spring in the top of the caliper under the anchor; then, install the other end into the lower caliper hole. NOTE: Hold the spring in the caliper hole with your thumb while prying the spring end out and under the anchor.
  14. Fill the master cylinder with fluid and bleed the brake system.

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.

Rear disc brakes


Raise the rear of the truck off the ground using jacks. Support the vehicle on both sides with jack stands to prevent it from tipping over. 
Loosen the lug nuts on the wheels and remove the wheels assembly and set aside, face up, to prevent damage.
Disconnect the caliper bolts and remove the brake caliper. Use mechanic's wire to fasten the caliper to your truck's side rail. Take out the outer disc brake pads followed by the inner pads.
Compress the brake piston into the caliper bore using a C-clamp. Replace the inner brake pads followed by the outer brake pads. Remove the C-clamp.
Remove the mechanic's wire from the caliper. Lay the caliper over the pads, fasten it down and tighten the caliper bolts with the torque wrench to 26 ft. lb.
Replace the wheels and lower the vehicle to the ground. Bleed the brakes if necessary and check the brake performance during a short test drive.
Good luck and hope this helps.

2002 tahoe breaks lock up during driving


It sounds like the rear calipers are bad. Raise the rear wheels and see if you can turn the tires. If you can't, open the bleeder. If you still can't replace the caliper. If you can turn the wheel after you open the bleeder, replace the brake hose to that wheel.
