Clean and Lubricate Brake Calipers (Integrated Parking Brake)
Correction Code 33013325 (Wheels Removed)
- 2024-01-25: Replaced Transport/Tow Mode steps with EPB Service Mode steps.
- 2023-05-17: Added Mobile Service notes to chock opposing wheels, service the front calipers, and then service the rear calipers.
This procedure describes a service performed when all four wheels have already been removed for another service, such as a winter tire to summer tire swap. If this procedure is to be performed standalone, then add the correction code 34012501 Wheels - Vehicle - Set (Remove & Install) to the Activity.
Perform these procedures in a manner that will be the least aggressive, considering the corrosion. Only when those steps are not effective, escalate the action to be more aggressive.Minimal corrosion, least aggressive to be effectiveMaximum corrosion, escalate to most aggressive to be effectiveFor example:First use a nylon brush to remove corrosion build-up from brake caliper abutment flats. If that is ineffective, escalate to a wire brush, and if that is still ineffective, escalate to a brake file.Use the brake file in single, forward strokes. Do not apply so much force as to remove any coating or metal from the caliper or carrier. 3 to 4 firm strokes of the file should smooth out the surface.First use a manual hammer and pin punch to remove retaining pins from the calipers before escalating to an air hammer. First use a brake pad puller to remove stuck brake pads before escalating to an air hammer with blunt chisel tip to break the pads free from the caliper.
Procedure
-
NoteIf the vehicle already has all four wheels removed for another service procedure, begin this procedure at step 5.
- If the vehicle has an air suspension, on the vehicle touchscreen, touch Controls (vehicle icon), touch Suspension, press and hold the brake pedal and touch Jack to activate Jack Mode.
- Move the vehicle to a 2-post lift. See Raise Vehicle - 2 Post Lift.
- Loosen the wheel lugnuts.
-
Raise the vehicle only
enough that the wheels no longer contact the floor.
NoteIf performing this procedure as a Mobile Service, chock opposing wheels to prevent rollaway, service the front calipers, and then service the rear calipers.
- Enable Service Mode from the touchscreen. See Service Mode.
- Unlock the Gateway. See Gateway Unlock.
- On the touchscreen, under Vehicle Info, touch Chassis, under Chassis, touch Brakes, and then in the diagram, touch EPB Service Mode.
- Read the text displayed, and under Parameters, from the Action target drop-down menu, select BOTH, from the Action type drop-down menu, select START, and touch Run.
- Raise the vehicle to a working height.
-
Remove all four wheels. See
Wheel Assembly (Remove and Install).
NoteIf performing this procedure as a Mobile Service, service the front calipers, and then service the rear calipers.
- Turn the front wheel hubs to point fully right.
- Use the appropriate pin punch to remove the retaining pins and anti-rattle spring from the front LH caliper.
- Use a caliper spreader to expand the brake pads and compress the pistons back into the front LH caliper.
-
Remove the brake pads from
the front LH caliper.
CAUTIONKeep the inboard pad and the outboard pad separate and organized.
- Remove the clip-on shim from the back of each brake pad, and then wipe the shims and back of each pad with a clean shop towel.
-
Use a brush and
Tesla–approved brake cleaner to clean the abutment flats, the piston faces,
the inner surfaces of the front LH caliper, the retaining pins, the
anti-rattle springs, the brake pad shims, and the brake pad edges and
surfaces that contact the caliper.
CAUTIONMake sure not to contaminate the friction material.
-
Apply a thin layer of
Tesla-approved brake caliper lubricant to the abutment flats in the front LH
caliper.
CAUTIONMake sure not to contaminate the piston seals or any rubber components of the caliper.
- Apply a thin layer of Tesla-approved brake caliper lubricant between the two shims that attach to the back of each brake pad.
- Install the shims onto the back of each brake pad.
-
Apply a thin layer of
Tesla-approved brake caliper lubricant to the brake pad edges that contact
the abutment flats.
CAUTIONDo not apply any lubricant to the back of the brake pads, and make sure not to contaminate the friction material.
-
Install the brake pads into
the front LH caliper.
CAUTIONDo not mix brake pads, as they have worn specifically to their respective position within the caliper.
- Use the appropriate pin punch to install the anti-rattle spring and retaining pins into the front LH caliper.
- Rotate the front LH rotor 180 degrees, and then use the Tesla-approved brake cleaner to clean any lubricant or debris from the rotor. Repeat.
- Turn the front wheel hubs to point fully left, and then repeat step 12 through 23 for the front RH caliper.
- Point the front wheel hubs to center.
- Use a brush and Tesla–approved brake cleaner to clean dirt and debris from the outside of the rear LH caliper connector and harness.
- Release the red retaining tab and disconnect the electrical harness from the rear LH caliper connector.
- Move the rear LH caliper outward to partially compress the caliper piston.
-
Remove the bolts (x2) that
attach the rear LH caliper to the rear LH carrier, remove the caliper from
the carrier, and then hang the caliper from an S-hook.
CAUTIONMake sure not to strain or kink the brake jounce hose.
- Remove the bolt that attaches the nameplate to the rear LH caliper, and then remove the nameplate from the caliper.
- Use the caliper spreader to compress the piston into the rear LH caliper.
-
Remove the brake pads from
the rear LH carrier.
CAUTIONKeep the inboard pad and the outboard pad separate and organized.
- Remove the abutment shims from the rear LH carrier.
-
Use the brush and
Tesla–approved brake cleaner to clean the abutment flats, the piston faces,
the inner surfaces of the rear LH caliper and rear LH carrier, the abutment
shims, and the brake pad edges and surfaces that contact the caliper or
carrier
CAUTIONMake sure not to contaminate the friction material.
- Install the abutment shims into the rear LH carrier.
-
Install the brake pads into
the rear LH carrier.
CAUTIONDo not mix brake pads, as they have worn specifically to their respective position within the carrier.
- Set the slots of the rear LH caliper piston face at the 12 o'clock and 6 o'clock positions.
- Install the nameplate onto the rear LH caliper, and then install the bolt that attaches the nameplate to the caliper (torque 9 Nm).
-
Install the rear LH caliper
onto the rear LH carrier, and then install the bolts (x2) that attach the
caliper to the carrier (torque 26 Nm).
NoteIf the bolt heads have become deformed, replace the bolts.
- Connect the electrical harness to the rear LH caliper connector, fasten the red retaining tab, and then perform a push-pull-push check of the connection.
- Rotate the rear LH rotor 180 degrees, and then use the Tesla–approved brake cleaner to clean any debris from the rotor. Repeat.
- Repeat step 26 through 41 for the rear RH caliper.
- If the vehicle already had all four wheels removed for another service procedure, return to that procedure. Otherwise, continue to the next step of this procedure.
- Install all four wheels, and then lower the vehicle so that the wheels just contact the floor but do not support the weight of the vehicle. See Wheel Assembly (Remove and Install).
- On the vehicle touchscreen, touch and hold Park to disable EPB Service Mode.
- Disable Service Mode. See Service Mode.
- Lower the vehicle completely.
- Final torque all wheel lugnuts to 175 Nm.
- Pump the brake pedal until firm.
- Remove the vehicle from the 2-post lift. See Raise Vehicle - 2 Post Lift.
- In areas where road salt is used, rinse the suspension components at each wheel with clean water.
- If the vehicle has an air suspension, on the vehicle touchscreen, touch Controls (vehicle icon), touch Suspension, press and hold the brake pedal and touch Standard to deactivate Jack Mode.
- Perform a cautious short drive comprised of multiple firm brake pedal applications to dry wet brake pads and rotors, and to verify braking performance.
