Clean and Lubricate Brake Calipers (Separate Parking Brake)
Correction Code 33013305 (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.

Use a 4mm 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 shim(s) from the
back of each brake pad, and then wipe the shim(s) 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.
- Front Brake Pads Only - Apply a thin layer of Tesla-approved brake caliper lubricant between the two shims that attach to the back of each front brake pad.
-
Install the shim(s) 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 4mm 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 step 23 for the front RH caliper.
- Point the front wheel hubs to center, and then repeat step 12 through step 19 for the rear LH caliper.
- Repeat step 12 through step 19 for the rear RH caliper.
- Use a brush and Tesla–approved brake cleaner to clean dirt and debris from the outside of the LH parking brake caliper connector and harness at the LH rear wheel.
- Release the red retaining tab and disconnect the electrical harness from the LH parking brake caliper connector.
- Move the rear LH caliper outward to partially compress the caliper piston.
- Remove and discard the bolts (x2) that attach the LH parking brake caliper to the rear LH knuckle, and then remove the caliper from the vehicle.
- Use a 10 mm x 1.5mm tap to chase the parking brake caliper mounting hole threads in the rear LH knuckle.
- Use a 3mm pin punch to remove the retaining pins and anti-rattle spring from the LH parking brake caliper.
-
Remove the brake pads from
the LH parking brake caliper.
CAUTIONKeep the inboard pad and the outboard pad separate and organized.
- Remove the upper sliding pin from the LH parking brake caliper, and then inspect for corrosion.
- If corroded, use the brush and Tesla–approved brake cleaner to clean the upper sliding pin, and then wipe with a clean shop towel.
- Lightly coat the upper sliding pin with Klueber GLK 1PF lubricant, and then reinstall the pin into the LH parking brake caliper.
-
Use a pick or tiny screwdriver to release the outer boot of the lower
sliding pin, and then move the pin partially outboard of the LH parking
brake caliper.
CAUTIONDo not remove the pin from the caliper.
- Apply Klueber GLK 1PF lubricant to the exposed surface of the lower sliding pin.
-
Move the lower sliding pin back into the LH parking brake caliper, use a
pick or tiny screwdriver to release the inner boot of the lower sliding pin,
and then move the pin partially inboard of the caliper.
CAUTIONDo not remove the pin from the caliper.
- Apply Klueber GLK 1PF lubricant to the exposed surface of the lower sliding pin.
- Move the lower sliding pin back into the LH parking brake caliper and fasten the boots to the pin.
-
Use the brush and Tesla–approved brake cleaner to clean the abutment flats,
