This procedure covers cleaning, inspecting, lubricating, and reinstalling brake caliper slide pins to ensure proper caliper movement and even brake pad wear.

Warnings

Tools required

Parts

• Caliper slide pin boot kit (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Chock rear wheels securely
3. Loosen wheel lug nuts 1/4 turn while vehicle is on ground
4. Raise front of vehicle and support securely on jack stands rated for at least 4 tons per side
5. Remove front wheels completely
6. Verify brake system is cool to the touch before beginning work

Procedure

1. 1

   Remove caliper slide pin bolts
   Locate the two caliper slide pin bolts on the rear of the caliper assembly. These are typically 13mm or 15mm hex head bolts. Using a socket wrench, remove both upper and lower caliper slide pin bolts. Support the caliper with your hand to prevent it from falling when the second bolt is removed.

2. 2

   Pivot caliper away from rotor
   Carefully pivot the caliper assembly upward and away from the brake rotor. Support the caliper by hanging it from the suspension or frame using a heavy-duty wire hook or bungee cord. Never let the caliper hang by the brake hose as this can damage the hose internally.
   ⚠Do not allow caliper to hang unsupported by the brake hose. Internal hose damage may not be visible but can cause brake failure.
3. 3

   Remove slide pins from caliper bracket
   Pull the slide pins completely out of the caliper bracket. Note their orientation and any differences between upper and lower pins. Inspect the rubber dust boots on each pin for tears, cracks, or deterioration. If boots are damaged, they must be replaced to prevent contamination and corrosion.
   ℹ️Damaged or torn dust boots will allow moisture and dirt into the slide pin bore, causing binding and uneven brake wear.
4. 4

   Clean slide pins and bores
   Spray slide pins thoroughly with brake parts cleaner and wipe clean with lint-free rags. Remove all old grease and debris. Use a clean rag wrapped around your finger or a soft brush to clean the inside of the slide pin bores in the caliper bracket. Spray brake cleaner into the bores and allow to drain. Inspect pins for scoring, pitting, or corrosion. Replace any damaged pins.
   ⚠Even minor corrosion or scoring on slide pins can cause caliper binding. Replace questionable pins rather than risk brake performance.
5. 5

   Inspect caliper bracket and hardware
   With slide pins removed, inspect the caliper bracket mounting bolts for proper tightness (do not remove unless replacing bracket). Check brake pad slide clips or abutment clips for wear or damage. Verify the caliper bracket itself shows no cracks or damage. Clean any rust or debris from pad contact surfaces using a wire brush.

6. 6

   Apply silicone brake grease to slide pins
   Apply a thin, even coat of high-temperature silicone brake grease to the entire length of each slide pin shaft. Do not over-apply; excess grease can attract contaminants. Ensure grease is applied all the way to the end of the pin. Verify you are using silicone-based brake grease, not petroleum-based lubricant.
   ⚠Use only high-temperature silicone brake grease. Petroleum-based products will damage rubber boots and seals.
7. 7

   Reinstall slide pins
   Insert each slide pin back into its corresponding bore in the caliper bracket, ensuring dust boots properly seat around the pin and in the bracket groove. The pin should slide smoothly with light resistance from the grease. If a pin binds or sticks, remove it, recheck the bore for contamination, and verify proper lubrication. Ensure boots are not twisted or pinched.
   ℹ️Slide pins must move freely by hand. Any binding indicates contamination, damage, or inadequate lubrication.
8. 8

   Reposition caliper over brake pads
   Before repositioning the caliper, verify brake pads are properly seated in the bracket. If pistons were not compressed, you may need to use a C-clamp or brake caliper tool to carefully compress the caliper pistons back into their bores to provide clearance over the brake pads. Position the caliper down over the rotor and brake pads, aligning the slide pin bolt holes.
   ⚠When compressing caliper pistons, brake fluid level in the master cylinder reservoir will rise. Check reservoir and remove fluid if necessary to prevent overflow.
9. 9

   Install and torque slide pin bolts
   Apply a light coat of silicone brake grease to the threads and under the head of each slide pin bolt. Insert both slide pin bolts and thread them in by hand. Using a torque wrench, tighten both caliper slide pin bolts to 35 Nm (26 lb-ft). Verify both bolts are properly torqued.
   ⚠️CRITICAL: Improperly torqued slide pin bolts can result in caliper detachment and complete brake failure. Verify torque specification is met.

    Reinstall wheel and torque lug nuts
    Position the wheel onto the hub and thread on all lug nuts by hand. Using a torque wrench, tighten lug nuts in a star pattern to 140 Nm (103 lb-ft). Double-check all lug nuts are properly torqued. Repeat entire procedure for opposite side.
    ⚠️CRITICAL: Improper lug nut torque can cause wheel detachment. Always torque in star pattern and verify final torque.

Reassembly

1. Lower vehicle carefully from jack stands
2. With vehicle on ground, re-verify wheel lug nut torque in star pattern
3. Pump brake pedal slowly several times until firm pedal is achieved before moving vehicle
4. Check brake fluid level in master cylinder reservoir and top off if necessary with Mopar DOT 4 brake fluid

Verification

• Pump brake pedal until firm - pedal should be solid, not spongy
• Start engine and verify brake pedal remains firm with engine running
• Check for any brake fluid leaks around calipers
• Test drive in safe area at low speed (under 15 mph) to verify brakes engage smoothly and evenly without pulling
• Perform several moderate brake applications to verify proper operation
• After test drive, recheck slide pin bolt torque and wheel lug nut torque
• Monitor brake performance for first 50 miles and address any unusual noises, pulling, or reduced braking effectiveness immediately
