So unfortunately a leaking master cylinder has made a mess of what was a relatively tidy engine bay
Fluid has leaked pretty badly from the master cylinder seal and cap, but it also looks like it has leaked between the master and booster flange... bit hard to tell. Paint is damaged along the inner guard, and also the right hand front suspension components.
I've done some reading through the various threads and there appears to be a range of areas that could cause this...
Here is what I know:
- Brakes seem to still currently work on the car, but;
- I jacked up the rear of the car and got my wife to stand on the brake pedal and only a small amount of resistance was applied to each rear wheel when I spun the tyre by hand. Definitely would lock up the rears. Pedal felt fine though.
- The car has been sitting for about a month since my last drive. When I took the master cap off, the rear reservoir was more of less empty, the front was full!
- When I re-filled the reservoir and pumped the pedal with the cap off, brake fluid squirted up out of the master (couldn't tell if it was front or rear. Luckily I lined the engine bay with rags...
- The master cylinder was "re-built" by the previous owner... Not sure if it was sleeved and a kit put through it or not..
- The rubber gasket looks new and the cap pulls down pretty hard
So where do I start...?
Could I assume the rebuild previously done wasn't done correctly?
Could sticky wheel cylinders cause this?
Could the brake lines be part blocked and cause this?
I'm thinking of taking off the master and sending it off for another overhaul .... makes sense since most of the paint has been stripped from it and it looks worse for wear! I was thinking of trying Knights Old School Brakes..
