Default Removing rear caliper

70 vert, passenger side rear caliper (and rotor): Need to remove to see why e-brake wont expand parking brake on this side

Are there the standard "through" bolts holding these on or are there the the two bolts lower near the backing plate to remove

There are also bolts holding the calipers together (one getting blocked by the brake line)

Thanks,

You must remove the brake line on the caliper first. Then there are two bolts on the back side holding the caliper on. You'll need a 5/8" deep socket. I use an impact wrench to remove them, but be careful if you do. I just finished doing this 20 minutes ago, before my brake fluid disaster hit...

Mark, do you remove the master cylinder lid to reduce presure for when you push back the pistons?

When you remove the line, what do you plug it with?

Thanks

MY70,

You will not need to remove the M/C cover.

I would recommend that you remove the brake line from the caliper with a fitting wrench rather then a standard open end wrench.

The caliper is held on with 2 bolts on the spindle I believe. Can be a real **** to remove if they haven't been taken off in awhile. I removed my calipers using a deep socket and a 24" breaker bar. It did take a little effort to remove them. When I put the calipers back on, I will coat the threads with never seize grease and torque to spec.

You can use just about anything to plug the line. A golf tee or a rubber "nipple" that you would use to close off a vacuum line will work.

Good luck!

I agree with the above post - use a line wrench. Don't try and use an open end wrench as you'll strip it. It's a 3/8" size.

I didn't remove my mc cover either. I never thought of plugging the open line; I just let it drip into a pan. I did one at a time, so the mc never ran out of fluid before I put more in.

Good luck with the mounting bolts. They are tough if they haven't been off in awhile!

BTW - if you use an impact (air) wrench, I have found that an impact socket is too fat to go around the bolt head, due to the trailing arm hub near the bolt. I use a regular deep well socket and carefully tap the trigger. You run the risk of shattering the socket, but so be it.

Can you post a pic of the bolts to remove to get the caliper off? Thanks
