need help with brakes
I noticed a puddle of brake fluid on the ground the other day so I replaced my caliper and brake hose since they have been on the truck for over 12 years. I used a one-man brake bleeder screw which is suppose to let air out and not in. When I pump the brake I get a firm peddle then whe I start the truck up the pedal hits the floor. Has anyone used these bleeder screws , if so how well do they work. I'm thinking about taking it to Midas on next week if I can't figure out the problem.

Jaye,
If you think the self bleeder screws are causing you problems, take them out and reinstall your old bleeder screws. They may not be letting enough air out when you go through the bleeding process. They seem like a real good idea; I'm just a little skeptical about them.

i had to replace the master cylinder on my mom's car yesterday. i have no help doing anything around here that i do. i bought a self bleeder system at my local part's store. it has a vacum pump that goes to a small container on one side, on the other side it connects to the bleeder. you pump vacum into the container then open the bleeder and it pulls the fluid out and into the container. i pulled all the old fluid out till i got clear fluid. it worked great and cost about 60 buck's. no more air in the system.

Did you bleed all four corners? You still have air in the system somewhere. I also used a Mighty Vac when I did bled the brakes on my truck. If you have no one to help you it works out well. I have not used the one-way bleeder screws but have heard that they work well...

I use a glass jar with some b. fluid in it and a piece of vacuum hose attached to the bleeder plug. If you are agile enough you can pump the pedal with your hand and watch the bubbles in the jar until no more come out. Air will not go back into the wheel cylinder if you have the hose submerged in the fluid and a tight fit at the bleeder plug.
