someone tried to bleed the brakes and broke the bleeder screw off. have you tried to lossen the bleeder screw on the other caliper, you might break that off trying to loosen it too.
best bet, get two reman calipers.
i always take out the bleeder screw and antisieze the threads, and when im done bleeding i smear some grease around the exposed threads.
I am going to counter what 84-250 said, no offense, but you do not want any kind of petroleum product anywhere near where the tiniest bit can get into the brake fluid. Petroleum will soften the seals and can cause brake failure. Contamination is difficult to completely remove from the system. Just bleed them every year or two like you should anyway and the bleeders will stay free. And don't crank down on them too hard or you will be fighting them next time. They don't have to be more than snug. And do yourself a favor and buy or build something like this:
Look for the "CUSTOM FORD POWER BLEEDER" on that page, 3 prong. I have one and it turns bleeding the brakes into a 15 minute thing. You can build your own also out of a plan pesticide sprayer that pumps up.
being Cheep all my life I got the lesson of a life time..
I had heck bleeding breaks on my 93 F150 so I went down and bought one of those Hand vacume pumps for break bleeding.
Having to do everything by myself this was 30.00 bucks well spent.
I never knew how easy it was to bleed breaks.
Like you. I have broken the bleeder screw and with the pump you just have to unscrew it once. pump then tighten it up, because your finished...
I have done it with the manual method, the vacuum and the pressure bleeders. The vacuum never worked that great for me, I could never tell when I was done because the vacuum would pull air in around the bleeder threads so you would see air in the hose no matter what. And you are constantly pumping vacuum and you have to worry about the master running dry. The pump up pressure bleeder pushes fluid into the reservoir as it's going out so unless you run that dry (1 qt) you don't have to worry about that, and the tube at the bleeder runs clear with no air when you're done.
You can build your own for about $15, I bought mine premade for about $50 and even at that price it was worth every penny.
Is there any way I can bleed it by loosining the caliper line?
Instead of replacing the whole caliper since the bleeder nut is gone?
Should I take this up with my old mechanic who was the last one to bleed my brakes?
Youi can't bleed the system by loosening the line, as it doesn't get air out of the caliper that way.
you could try going back to the guy who MIGHT have broke it, maybe he'll pony up and fix it for you.
Or you could just bite the bullet and fix it yourself. You'll need a new bleeder valve, an easy out, bucket to put the caliper in while you work on it (so brake fluid doesn't get all over the place) and a quart or two of brake fluid. You'll also need a ride in case you screw the job up and have to replace the caliper.
Might as well get it done right, and just do it yourself.
Has anyone ever tried the bleeder nipples with the ckeck ball valve in'em? I saw them for the first time the other day and thought it might be a good way to bleed brakes by yourself. The description said you loosen the nipple enough to let the brake fluid start coming out and the one way check ball valve keeps air from being sucked back in...
Some people swear by them but I don't see how air doesn't get sucked back in past the threads. Bleeders don't seal with the threads, they seal with the taper at the end. Maybe carefully teflon taping them would do the trick.
