Can’t take out master brake cylinder

It appears that someone installed the top bolt on my master brake cylinder backwards, so I can’t take it out. I physically cannot get the bolt out no matter how much i try. Any suggestions?

Pull the bracket off of the car (4 bolts) and then remove the bottom bolt. That will allow the cylinder to move forward enough to remove that captive bolt, which is by design.


I swear, hon, this is the last thing I should need....

Mind that the 4 top bolts thread into a bracket inside the driver footwell that carries the brake pedal lever and pivot assembly.
When bolts are removed, the assembly will drop to the footwell floor.
And that when re-assembling, you may need a helper.

Welcome to the club! You'll try this again, some years from now, and might do the same thing. I know I have.

As long as only those four bolts are removed, no problem... at least on my car. In fact there are ten bolts in mine. Four on each cylinder bracket and two in the back. I had both my brackets off earlier this year and the inside plate didn't move. It was a different story the first time I did it. sad smiley

Yes I just installed brake and clutch Masters as long as you do not remove the backing plate and just run a tap to clean threads before replacing same all good. I also remounted with SS 1/4 x 28 bolts

In general, SS bolts are weaker than carbon alloy steel.
They are also 'softer', so cross threading can occur more easily.
There are a number of SS alloys having different characteristics, so it's worthwhile to be sure what alloy the bolts are made of.

Be prepared to pay premium prices for premium SS alloys.
