Bleeding the brakes...

[andercee]

I recently changed all the brake pads on my 92 cutlass supreme s...

and i guess i got some air in the lines because i had to remove one of the calipers


Bleeding brake lines seems like an easy job but I haven't done it before on this car and I was wondering if there is any weird kinks i should be prepared for.

Thanks

You shouldn't have gotten air in the lines just by removing the calipers but if somehow you did you'll need to bleed them. You'll need another person to help you. All you have to do is have is have someone pump the brakes and hold pressure on the pedal, then get to the brake caliper and find the bleed port, then while pressure is applied, open the valve port and let the fluid bleed out, then close the valve while the pressure is still being applied. Don't let up on the brake pedal until the valve is closed. Repeat this several times until you feel or hear air being displaced from the lines. Make sure to keep your brake fluid reservoir filled as bleeding will lower the fluid. You should also have the motor running when bleeding. That should fix you up.

thanks, i'm going to do this in the morning.. i had to remove the whole brake caliper from the car which included removing the brake line.. the problem has gotten better because i guess the air finds a way out eventually.. but i'm still goign to do it just to be safe... only problem that is that since the rear brake pads have such a longer life than the front, that the bleed valve has rusted shut.. so hopefully some wd-40 will take care of that problem..

Use a brake bleeder wrench which you can find from your local automotive stores. Do not use a regular wrench otherwise you will strip the bleeder valve.
