MPP.R rear BBK install

[stevehifi]

Hi Guys,

Just wanted to post some information the MPP.R BBK install for those who might be interested.

Tools needed:
-21mm socket
-10mm (1/4" drive)
-T-27 torx (1/4" drive compatible)
-E14 torx socket
-1/2" drive
-3/8" drive
-extensions
-torque wrench
-9V battery with wiring adapter to positive and negative clips/terminals
-motor oil
-blue loctite

Steps:
-Chock all 4 wheels
-WORK ON A FLAT SURFACE
-Put car in Tow mode
-Untighten rear wheels
-Lift rear end gently and make sure car doesn't move (re-check wheel chocks)
-Remove both rear wheels

-Remove power connector for rear parking brake (pull on grey clip and wiggle to release)
-use 9V battery on power adapter socket (positive to contact on rounded end, negative to contact on square end)
-you will hear the motor retract and eventually stop (disconnect power at that point)
-untighten 10mm bolt holding e-brake cable bracket to housing (lower back side of motor)
-Remove rear parking brake motor using T27 socket (2 torx bolts), do it gently as the bolts can be somewhat still tight
-Remove e-brake motor (this will allow you access to the middle torx bolt for the stock caliper clamshell)
-Remove 3 E14 torx bolts from clamshell (you will need long 1/2 ratchet and/or breaker bar since they are tightened pretty well)
-Remove stock clamshell and set aside
-Remove stock rotor (10mm bolt)
-Remove inner pad and press piston inboard for clearance

-Fasten new outer pad (or use existing from old clamshell) to new MPP.R clamshell with provided hardware
-install inner pad (if using newer one)
-install new MPP.R rotor
-put loctite on 3 E14 torx bolts and a dab of oil under bolt heads
-install new MPP.R clamshell and torque 3 bolts to 80lb-ft
-reinstall e-brake motor with T-27 torx 2 bolts
-reinstall cable bracket with 10mm bolt
-reconnect e-bracket power connector

Check your work and make sure everything has been tightened properly

it was a B**** to install. I had call MPP for help. We figured it out but we had to take out that "Remove rear parking brake motor"

Actually the install went very smoothly but yes the ebrake motor did need to be removed and that’s a step MPP should put in their instructions

Thanks for the tip! These are definitely on my short list for the spring!

FWIW I believe this only applies to the updated rear parking brake (you can tell by the unfinished inner clamshell). The older design did not require removal of the parking brake motor.
