So my brake fluid was very low on my Mini. Coming home a car show two weeks ago I noticed my brakes pretty well shot. It braked, but I was pushing air into the lines and I knew I was going to need to bleed the brakes and all that. I took it up to Toyota today, and my brother who is a tech put it up on a lift, we did the bleed, replaced with the recommended DOT 4 fluid and all was good. Sort of...

On the front right side, the disc brakes looked good. However, the left side, there are pieces within the caliper that are missing. I have no idea how this happened. Here are pictures of it, the first being the correct set up on the right, the second the left.



What are the guts that I am missing called? I see that I am missing a pin as well. Is this the part that needs to be replaced?

 

You are correct. Those are retaing pins and anti-rattle clips.

Are you sure there are no leaks in the system? Did you check the rear cylinders? Do the master cyl seals hold pressure? Did you adjust the rear shoes out & emergency to 3-4 clicks off the floor?

 

Yes they are retaining shims and pins, are you finding difficulty getting them if so I maybe able to help .........
