Removal

For additional information see Removal Notes. Fundamentals and Basics

1. Use a clean siphon or suction hose to remove a portion of the fluid from the master cylinder. Discard the removed fluid.

CAUTION: System contamination may result if anything other than a clean device is used to remove fluid from master cylinder.

NOTICE: Removing some fluid will prevent fluid from overflowing from the master cylinder when the caliper pistons are pressed into their bores.

2. Raise the vehicle and install safety stands. Remove wheel and tire assembly.

Compressing Caliper:

3. Use an eight-inch C-clamp to move the piston back into its bore as follows:

a. Place the head of the C-clamp against the caliper, and the screw end of the C-clamp against the outer pad below the spring clip.

CAUTION: Do not position C-clamp on the spring clip. Also, do not compress piston further than is required to disengage torque buttons from caliper. Damage to the spring clip will result. Replace pad if spring clip is bent or damaged.

CAUTION: Do not attempt to "bottom" the piston in the bore at this time. Use an old, worn out brake pad or block of wood and the C-clamp to bottom the piston once caliper is removed from rotor, and the pads are removed from the caliper.

b. Tighten the clamp until the torque buttons just clear the caliper (about 3 mm [1/8 in]). Remove the C-clamp.

CAUTION: Do not use a screwdriver or similar tool to pry piston away from the rotor.






4. There are three types of caliper pins used: a single tang type, a double tang type and a split-shell type. The pin removal process is dependent upon how the pin is installed (bolt head direction). Remove the upper caliper pin first.

On some applications, the pin may be retained by a nut and torx-head bolt (except the split-shell type).

Caliper Pin - Bolt Head On Outside:

If the bolt head is on the outside of the caliper, use the following procedure:

Separation Between Bolt Head And Caliper Pin:

^ From the inner side of the caliper, tap the bolt within the caliper pin until the bolt head on the outer side of the caliper shows a separation between the bolt head and the caliper pin.
^ Using a hacksaw or bolt cutter, remove the bolt head from the bolt.
^ Depress the tab on the bolt head end of the upper caliper pin with a screwdriver, while tapping on the pin with a hammer. Continue tapping until the tab is depressed by the v-slot.
^ Place one end of a punch (1/2 inch or smaller) against the end of the caliper pin and drive the caliper pin out of the caliper toward the inside of the vehicle. Do not use a screwdriver or other edged tool to help drive out the caliper pin as the v-grooves may be damaged.

Caliper Pin Installation - Nut On Outside:

If the nut end of the bolt is on the outside of the caliper, use the following procedure:

^ Remove the nut from the bolt.
^ Depress the lead tang on the end of the upper caliper pin with a screwdriver while tapping on the pin with a hammer. Continue tapping until the lead tang is depressed by the v-slot.
^ Place one end of a punch (1/2 inch or smaller) against the end of the caliper pin and drive the caliper pin out of the caliper toward the inside of the vehicle. Do not use a screwdriver or other edged tool to help drive out the caliper pin as the v-grooves may be damaged.

5. Remove the lower caliper pin per the procedure in Step 4.
6. Remove the caliper from the rotor. If the caliper is to be removed for service, remove the brake hose from the caliper.

CAUTION: Do not let the caliper hang with its weight on the brake hose.

7. Remove the outer lining. Remove the anti-rattle clips and remove the inner lining.
