I bought a caliper rebuild kit that included new pistons, O rings, dust seals and caliper slide pins. I didn’t bother to put the anti rattle clips on. The bores looked really good with no pitting.

It’s a 70k mile car and the caliper mounting brackets and any other wear points look good.

When I rebuilt the calipers the pistons seemed to slide into the bores easy enough.

It is a one piece proportioning valve that is not available new.

I had planned on doing a manual bleed in the morning, but now it may be next weekend.
I may need to simply replace the DS caliper and see what happens.

Thx
