booster mc replacement

[doughboy68]

Hey all....

I just replaced the booster and master cylinder as one unit. I bled the brakes, but they are still squishy. Will the master cylinder bleed air as well when doing each wheel separately or do I need to remove the master cylinder and bleed it first, then the rest?

Thanks in advance!

You really should bleed the air out of the MC before installation, but it can be done with the MC on the truck. You need a MC bleed kit, an auto parts store should have them. It consists of two fitting that screw into the side of the MC where the brake lines go. The fittings have hoses attached to them that you loop back into the MC reservoirs. Fill the MC with brake fluid, then have someone slowly apply and release the brakes until no more bubbles appear. At this point the air is out of the MC, and you can removed the bleeder fittings and reinstall the brake lines. You will still need to re-bleed your brakes.
Here is a kit that Summit sells:
