Update-
LF caliper still dragging after brake hose replacement in front both sides.
Dilemma, to rebuild master or replace? Had to remove master to find what bore size it was to order rebuild kit.
Not a lot of fun removing as metal brake lines attached on bottom of master are a pain to get undone.
After getting master out and inspecting I noticed fluid in brake booster.
Searched for that and I don't need that problem of sucking fluid into engine so on we go. My brake booster is one ugly dude even though it was working (not sure how much is right) I decided to remove it as well.
After moving the power steering reservoir with hoses attached out of the way and then removing battery and oh that relay next to battery has got to come out as well. Dip stick too. Luckily blue manual tells me about pin at brake pedal and with some correct words applied I was able to remove the brake booster.
Now what to do? I managed to suck (with a baster) a cup or more of brake fluid out of the booster.
Decided to see what the options for the booster are?
No new ones.
No rebuilt ones.
Did some googling and found a Triumph site talking about a company in Indiana that rebuilds. Called them and they don't rebuild ATE as he said he could not get the parts but gave me the name of a company in CA.
Looked them up and they listed many BMW units but said they did not do the CS units.
Well another phone call and a little waiting and Kyle said he could rebuild my booster. He had the parts. $189.75 + ship.
So today I sent all 17 lbs of booster off to CA to be rebuilt.
Can't tell you yet what it looks like or how it works.
We will be gone for about 12 days so might be waiting for me when I get back.
Also ordered a new master. At least something on my coupe will be new and work.
Here's the name:
Power Brake Exchange in San Jose CA.
