2020 Tesla Model 3 Performance rear brake pad change.
Tracking a M3P will use up the stockpads quickly. The front pads seem to last longer than the rears. Fronts are easy to change but the rears with the parking brake will need special attention. Below is the writeup for replacing the rear pads. Carbotech XP10 used.
Tesla rear brake job
1 Will need channel locks, screwdriver flat, brake pad spreader 12 V battery with alligator clips, torx socket, torque wrench set to 77 foot pounds, bungy cord, brakecleen, compressed air blower nozzle, portable grinder ( for tabs??) syringe to suck out fluid
2 need to remove brake fluid from Reservoir or will overflow
3 when car is jacked up put car in tow mode. Immediately remove both rear parking brake electrical connections. Tow mode will remain on entire duration at this point
4 remove torx caliper bolts. Spread brake pads apart enough to remove from rotor area. Use bungee cord to hang caliper to upper control arm. Attach negative alligator clip from battery to square end of plug, attach positive alligator clip to round area of plug. Apply current at five second intervals. Approximately 10 to 15 seconds required to retract parking brake piston. At that point use either channel locks, screwdriver with wooden block, or brake pad spreader’s with old pad to push piston all the way back to flush with caliper body.
5 once piston is retracted and old pads are out, use brakecleen and compressed air, to clean brake pad wing support areas where pads insert in the caliper. Check new pads to see if wings fit into tabs in outer area of caliper. May need to grind less than 1 mm on the upper end of pads tabs. Pads require tight fit and should not jiggle in outer portion of caliper. If ground too much use that pad on the inside portion of the caliper (in spring clips) adjacent to the piston.
6 once new pads are installed reapply caliper to car, torque bolts to 77 foot pounds, gently depress brake pedal few times to pump up piston/ pads to rotor and then reconnect electrical connections and paint mark bolts
7 if doing only rears, you’re finished. If doing fronts proceed with fronts. Once everything is together paint marked and checked, gently depress brake pedal again to confirm firm pedal and remove the vehicle from tow mode. Vehicle then is finished
8 Bed pads on highway if needed.
