This procedure covers cleaning, inspecting, and lubricating brake caliper slide pins to ensure proper caliper movement and even brake pad wear without opening the hydraulic system.

Warnings

Tools required

Parts

• Caliper slide pin grease (synthetic high-temp) × 1 — Use OEM specification or Mopar-approved silicone brake grease
• Thread locker (medium strength) × 1 — Loctite 243 or equivalent

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Chock rear wheels securely
3. Loosen front wheel lug nuts 1/4 turn while vehicle is on ground
4. Lift front of vehicle with floor jack at manufacturer-specified jacking point
5. Support vehicle securely on jack stands placed at frame rails
6. Remove front wheels completely and set aside

Procedure

1. 1

   Inspect brake system condition
   Before starting work, visually inspect brake pads for remaining thickness (minimum 2mm), rotor condition, and caliper for fluid leaks. Check rubber slide pin boots for cracks or tears. If boots are damaged, pins should be replaced as contamination has likely occurred.
2. 2

   Remove caliper guide pin bolts
   Locate the two caliper guide pin bolts on the inboard side of the caliper. These are T55 Torx bolts. Remove both bolts completely and set aside. Note their condition - if bolt heads show rounding or damage, replace bolts before reassembly.
3. 3

   Remove caliper from bracket
   Carefully pivot the caliper upward and away from the rotor. Do not disconnect the brake hose. Support the caliper with a bungee cord or wire hook attached to the suspension or frame to prevent strain on the brake hose. Never allow caliper to hang freely by the hose.
   ⚠Supporting the caliper weight improperly can damage the rubber brake hose, leading to brake failure.
4. 4

   Remove slide pins from bracket
   The slide pins are located in the caliper bracket. Pull the rubber dust boots away from the bracket bores. Grip each slide pin and pull straight out from the bracket. If pins are seized and won't pull out by hand, use pliers gently on the pin shaft (not the boot). Note the orientation and which bore each pin came from as they may be different lengths.
5. 5

   Clean slide pin bores
   Spray brake parts cleaner into each slide pin bore in the caliper bracket. Use a clean, lint-free rag wrapped around a finger or small brush to thoroughly clean inside each bore, removing all old grease, dirt, and corrosion. Inspect bores for scoring, pitting, or damage. The bore surfaces should be smooth.
6. 6

   Clean and inspect slide pins
   Thoroughly clean each slide pin with brake parts cleaner and wipe dry with a lint-free rag. Inspect pin surfaces for corrosion, scoring, bending, or wear. Pins should be perfectly straight and smooth. Check rubber boots for any cracks, tears, or deterioration. Replace pins and boots as a set if any damage is found.
   ⚠Even minor corrosion or pitting on slide pins can cause binding. When in doubt, replace the pins.
7. 7

   Lubricate and reinstall slide pins
   Apply a thin, even coating of synthetic high-temperature brake grease to the entire shaft of each slide pin. Do not over-apply - excess grease will attract dirt. Insert pins back into their original bores in the bracket, pushing firmly until fully seated. Pull the rubber dust boots over the bracket openings, ensuring they are properly sealed with no gaps or tears.
8. 8

   Reinstall caliper onto bracket
   Remove the support holding the caliper. Carefully pivot the caliper back down over the brake pads and rotor, aligning the caliper mounting holes with the slide pins. Ensure brake pads are properly positioned and caliper seats fully against the bracket.
9. 9

   Install and torque caliper bolts
   Apply a small amount of medium-strength thread locker to the threads of both caliper guide pin bolts. Insert bolts and hand-tighten. Using a torque wrench, tighten both caliper bolts to specification in a crossing pattern. Verify both bolts are fully seated and properly torqued.
   ⚠️Improperly torqued caliper bolts can back out during operation, causing complete brake failure.
   Torque spec

   Caliper Bolts102 Nm (75 lb-ft)
10. 10

    Reinstall wheel and lower vehicle
    Reinstall the wheel onto the hub, ensuring it seats properly. Hand-thread all lug nuts to prevent cross-threading. Snug lug nuts in a star pattern with a socket, but do not torque yet. Repeat all steps for the opposite side if servicing both calipers. Once both sides are complete, lower vehicle until tire just contacts ground (still supported by jack). Torque lug nuts to specification in a star pattern. Fully lower vehicle and remove jack stands.
    Torque spec

    Wheel Lug Nuts156 Nm (115 lb-ft)

Reassembly

1. If servicing one side at a time, repeat entire procedure for opposite front caliper
2. Verify both caliper bolts are torqued properly on each side
3. Verify all lug nuts are torqued to specification in star pattern
4. No brake bleeding is required unless hydraulic system was opened

Verification

• Before driving, pump brake pedal several times to ensure firm pedal feel and proper pad seating
• Start engine and verify brake warning light is off
• Perform a low-speed test drive in a safe area, checking for normal brake operation and even braking without pulling
• Listen for any unusual noises during braking that could indicate caliper binding
• After test drive, verify wheels are not excessively hot compared to each other, indicating a dragging caliper
• Re-check wheel lug nut torque after driving 50-100 miles
