Removal & Installation


NOTE Using a brake pedal holding tool, depress the brake pedal past its first inch of travel and hold it in this position. This will isolate the master cylinder from the hydraulic brake system and will not allow brake fluid to drain out of the reservoir while the brake lines are open.

1. Before servicing the vehicle, refer to the Precautions section.
2. Remove or disconnect the following:
   
   Negative battery cable Rear wheels Banjo bolt retaining the brake hose to the caliper. Be sure to plug the end of the brake hose or cover it with a plastic bag to prevent contamination from entering the hydraulic system. Caliper guide pin bolts Caliper assembly from the brake adapter by rotating the bottom of the caliper away from the rotor, then lift the caliper with the pads away from the adapter abutment Brake pads by pushing (outboard) or pulling (inboard) from the caliper fingers and piston

To install:

1. Completely compress the caliper piston
2. Install or connect the following:
   NOTE The outboard pads are side oriented, make sure the spring clip is installed so it is positioned downwards when the caliper is installed.
   
   
   Inboard pad clip against the piston cavity and press the pad until the clip is seated making sure the pad backing plate is flush against the piston
   
   
   Outboard pad making sure the locating pins are positioned against the ramps. Slide the pad onto the caliper and ensure the locating pins are squarely seated into the holes on the caliper and the pad is flush against the caliper fingers.
   
3. Make sure the abutment shims are in place on both slide abutments.
4. Retract the caliper guide pins to clear the caliper adapter bosses.
   
   Brake caliper. Staring with the upper end, position the caliper and shoes over the rotor and align the outboard pad upper edge with the caliper slide abutment. Rotate the lower end of the caliper into position Caliper guide pin bolts and tighten to 200 inch lbs. (23 Nm) Banjo bolt with new washers on each side of the hose fitting and tighten to 35 ft. lbs. (47 Nm) Wheels Negative battery cable
   
5. Bleed the brake system and road test the vehicle

For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!!

A special tool is required to compress the caliper piston on the rear brakes-don't use a C-clamp on the piston.
Raise the vehicle and remove the tire. The rear calipers have only one guide pin. Remove this pin and raise the caliper. Remove the old brake pads. Using the special tool compress the caliper piston-the piston will have one or two slots on it. These slots must in the correct position to remount the caliper. Install the new brake pads and slide the caliper back over the rotor and replace the guide pin. If the caliper doesn't slide over the rotor you'll need to reset the slots on the piston. Replace the tires and you're ready to go.

Remove the old Brake Pads

1 Park your car on a level surface. If you have a stick shift car make sure the car is in gear. Do not set the parking brake. Place blocks in front of the front tires so the car does not move while you are working on it.

2 Open the hood of your car and locate the master cylinder. If necessary, remove brake fluid until the level in the container is less than half full. A turkey baster is a good tool for this. Put the brake fluid in the plastic container and dispose of it the way you dispose of motor oil.

3 Raise the rear end of your car with your car jack. Remove the rear tire or wheel assembly.

4 Remove the parking brake cable from the back of the caliper. Use the pliers to remove the cable clip (restraining clip).

5 Use the socket wrench to remove the upper mounting bolt from the caliper. If the upper guide pin moves while you do this, use a back-up wrench to hold the upper guide pin.

6 Rotate the caliper downward, pivoting it on the lower caliper bolt. Remove the inner and outer brake pads from the caliper.

Install the new Brake Pads

1 Turn the caliper piston clockwise to retract it into the caliper housing. Insert the new brake pads into the caliper.

2 Swing the caliper upward and into place. Apply a thin coat of thread locking compound to the bolt and use the socket wrench to tighten the bolt to 271 inch lb. (35 Nm).

3 Reattach the parking brake cable to the caliper.

4 Replace the tire wheel assembly. Lower the car to the ground.

5 Pump the brake pedal a few times to seat the brake pads. Do this before trying to move your car.

6 Add fluid to the master cylinder container to replace any you removed before you removed the old brake pads.

7 Season the brake pads by making only gentle stops when you are driving for the first week after you install the new brake pads. Try not to do any hard stopping when you are seasoning the brakes.

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.
