Brake service mode

Doesn't work on tundras

Edit: just realized it's just to disable the ebrake

 

Which bolts gave you grief? Caliper bracket bolts are easy, the caliper pin bolts are tough if you don't have means of holding the sliding pin from spinning

 

It’s in the manual

 

The bolts were all easy to take off. Idk how to make the caliper piston retract. Some have mentioned to leave the truck in neutral, which I prefer not to do especially when truck is jacked up. How does one retract the caliper piston correctly?

 

Turn off the auto ebrake, open up the brake fluid reservoir, apply 12v to the ebrake plug to retract the internals, then use a caliper spreader to push the piston in. You can also turn the piston clockwise and that will also drive it in. I didn't go this route as the seal was twisting. I applied 12v and pushed it in little by little.

 

this was my thought, but apparently you need to do more

 

My 2 cents to help someone that may be doing this in the future - Just replaced my rear rotors and pads. Ended up leaving the truck in Neutral jacking up one side at a time with wheel securely caulked. I removed the ebrake motor and manually compressed the piston while backing the ebrake motor out with a torx bit. Not sure this is the best way but it worked. It was my first time dealing with an electronic parking brake so I had to improvise some.

 

I essentially used TakiEvo's recommendation in this post. Thanks TakiEvo!
