Clean And Lubricate Brake Calipers (Integrated Parking Brake)

Correction code 33013325 1.20 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so. NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure proper PPE is worn when performing the below procedure.

2024-1-24: Add caution on making sure the front brake pad clip is properly installed.

Warning

Wear respiratory protective equipment in addition to standard personal protective equipment when servicing brake components.

CAUTION

Do not mix brake pads, as they have worn specifically to their respective position within the caliper. Keep the inboard pad and the outboard pad separate and organized.

CAUTION

Apply lubricants sparingly and do not permit lubricants to contact rotors, brake pad friction surfaces, or rubber brake components, especially piston seals. Use a Tesla-approved brake cleaner and clean shop towels to remove mis-applied lubricants.

Note

Brake calipers in this procedure may not be the same color as those installed in a particular vehicle, however the actions to perform the service are the same regardless of caliper color.

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 extent of corrosion. Only when those steps are not effective, escalate the action to be more aggressive.

Figure 1. Minimal corrosion, least aggressive to be effective

Figure 2. Maximum corrosion, escalate to as aggressive to be effective

For example:

First use a nylon brush to remove corrosion build-up from brake caliper components. If that is ineffective, escalate to a wire brush, and if that is still ineffective, escalate to a brake file.
CAUTION
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 brake pad puller to remove any stuck brake pads before escalating to an air hammer with blunt chisel tip to break the pads free from the caliper.

Note

On severely corroded brake calipers, the rapid vibration of an air hammer can help break up the corrosion and loosen any guide pins and brake pads stuck within the caliper. Apply the blunt tip of the air hammer to the locations where the guide pins pass through the brake pads.

Note

If the brake pads have worn to the point of replacement, or the condition of the pad is such that braking safety is affected, replace the pads. Clean and lubricate other brake components as originally intended.

Note

Replace any anti-rattle springs and bolts that are excessively corroded.

Procedure

Note
