Rear Pads and Rotor replacement process
I replaced my back brake pads and rotors this morning with aftermarket Powerstop kit K7340.
A few pointers:
The release tab on the electric break coupling is simply pushed back with you thumb to release the connector (see photo).
When using the T-45 Torx to back off the pressure on the caliper piston, turn it clockwise like your tightening it (see photo).
I used a ratchet with ¼ “ socket and a T-30 Torx to remove the electric motor with ease, this gives you way more torque and control than a driver handle with the Torx.
Removing the brake line retaining bolt allows the entire caliper to rest safe on the floor with no strain at all on the break line…made it real simple to work on the electric motor removal.
Here are the bolt sizes and torque levels.
19 mm lugs nuts 80 ft/lb
12 mm bolt for brake line holder
13 mm flange bolts 26 ft/lb while holding caliper pins with 17 mm open end wrench
17 mm Caliper bracket bolts 80 ft/lb
Loosening the old rotors off the hubs was done using two 8 x 1.25 mm bolts turned 90 degrees (see photo).
The philips head screw that holds on the rotor was loosened with an impact driver then ratchet with philips head from the impact driver.
There is no need to do any sort of maintenance mode anything. After your all done pump brakes a bit to get pistons back out.
Activate the electric parking brake (it will wind out longer than typical). Then (with engine running) cycle the electric brake twice, light on dash goes off and everything is back to normal.
