Bleeder Bolt Broke "HELP"
 

Last night, I had just finished putting on the front and rear brakes on my 98 Honda Civic Cx, when all that I had left to do was to bleed the system. In preperation of this task, I had previously noticed that both bleeder bolts on the back bakes were excessively corroded with rust. So, I sprayed them both with Kroil penetrating oil, whereas one bolt turned, and the other one broke.

At this point, I'm thinking that the most practicle way for me to fix this problem, would be to remove the wheel cylinder itself. The question however, is how I should remove the broken bleeder bolt.

I would replace the slave cylinder which should have new bleeder valve installed.

Use a small drill to excavate the bleeder bolt: drill inside the bleeder bolt whilst not damaging the threads of the completely disassembled wheel cylinder, then screw in the new bleeder bolt. Remove new bleeder bolt and flush debris from the wheel cylinder. Reassemble wheel cylinder. Much easier to replace the wheel cylinder with new one.

Really???????????????????????????????????????????? ????????????????????????

replace wheel cylinder, they are 12.99 at autozone and maybe replace the other at a min I would replace the other bleeder screw if sold seperately.

First, if you were just changing the brake shoes and didn't open any hydraulic lines, you should not have to bleed.

Replacing the complete wheel cylinder is the way to deal with a broken bleeder bolt, but then you have to hope that the line connection isn't rusted together. Soak it in penetrating oil before trying to remove. Always use a line wrench (flare nut wrench) on the flare nut.

Initially, a rusty brake line is what I had feared, which is why I hoping to find a way to get the busted bleeder screw out in the first place. After taking some time out from being frustrated, I was able to disconnect the brake line, along with the wheel cylinder from the backing plate. This was not a rusty as I had feared, and like most people suggested, I took the more practical route and bought a new wheel cylinder.

Next time use a tourch to heat up the area around the screw, wiggle the screw gently back and fourth. be patient
