I was going to flush out the brake master cylinder, as well as the brake lines but noticed when I went to clean out the master cylinder that there was a fare amount of sludge on the bottom of the bowl, close to 1/32 of an inch or so.
Trying to gravity bleed the lines didn’t work at all, and I’m guessing that I’ve got some blockage in there somewhere.
With as much sludge as I found, and with new calipers and wheel cylinders going on the car, I decided that it would be in my best interest to replace the master cylinder as well, it looked bad enough that I didn’t want to chance it.
So with the master cylinder off the car, the calipers and wheel cylinders off, so all that’s left is just the brake lines and nothing else. What would be a good way to flush them all out?
Maybe compressed air? A little paint thinner or lacquer thinner? Some solvent? Or just feed through brake fluid until it’s good and flushed.
My concern is that I have sludge in the brake lines and with all new calipers, master cylinder, and rear wheel cylinders, I want to be sure I can get the brake lines as clean as possible before I reinstall everything.
Any suggestions or ideas?
