I'm working on replacing my trailing arm bushings and discovered a brake fluid leak from a crack in the metal brake line behind the rear drum. The main problem is rust from canadian winters. I want to replace the brake line but everything is badly rusted.
To complicate things further the bleeder valve won't open, and the two wheel cylinder mounting bolts are stuck because of rust. I want to stop the leak and replace the rusted section of line. I've used a heat induction gun and penetrating fluid on the bolts but didn't have any success with doing that. It was hard to focus the heat on the right area because it's tight.

How can I remove the brake cylinder with rusted mounting bolts?
How about disconnecting the hard brake line from where it connects you the rubber brake hose?

Any tips?

I got this far today and cut off the right wheel cylinder

So now I'll replace the rear passenger side wheel brake cylinder and brake line. My question is whether I can get away will only bleeding the system from this one bleeder?I'm pretty sure I won't be able to open the opposite rear brake bleader due to corrosion. What do you guys think?

 

gonna have to bleed both sides, sorry. Sometimes a grinder or cutting torch is your only option.
Good luck

 

I bled both sides and replaced the right line. and replaced the fluid. Repair was a success.

 

Was lurking, reading your story.. glad to hear you got both sides repaired and bled! awesome!
