The Stovebolt Site Forums The Parking Lot Big Bolts 51 gmc 3 ton brake mc problems

I have had nothing but trouble trying to get my brake work started on my ol 51. First off, the head was terribly stripped on the mc filler bolt. I eventually bought an ez out, started drilling only to find the bolt was no bolt at all, just a washer with a head on it and very hollow. I decided to remove the mc but I couldn't get to the back bolt inside the channel/bracket. I decided to try and remove the whole assy but got to the last bolt and it is too tight to get to and I'll have to remove several more parts just to get to that bolt. Am I crazy or is this job really as hard as it seems to be ? I am at an empass and not sure how to go from here. Any help very appreciated

Hy Red63, I'm sorry you're having a harder than normal time trying to overhaul your brake system, it might help to remember that these parts have been together for 64 years. Brake fluid attracts moisture from the air, that moisture starts corroding the system from the inside. When dissimilar metals corrode in close contact like your master cylinder cap they tend to lock together. You just need to do whatever you have to to remove components to overhaul them, try to save the fittings but don't worry about destroying the brake lines. You will feel great when you have it all done, but it definitely can be a hassle, keep plugging away at it, good luck.

Thanks, 3b for the encouragement. I got th mc off this afternoon with the help of my son-in-law. Now to get the filler cap off... It appears to be rusted so badly it seems as one with the housing. I will work on that for awhile now
