excessive pedal travel with Wilwood brakes!

You do NOT need to replace the factory master cylinder with an aftermarket master. The factory master will work perfectly. Gravity bleed your brakes. Start with the RR, LR, RF, and end at the LF. I've been using 6 piston fronts for about a decade and 4 piston rears for several years now with the factory master cylinder.

Could it be the booster itself? Im not hearing any vacume leaks or anything.I bleed the brakes just like you said above. Ive bleed it every possible way.

OK so........ I feel kinda stupid now. Was looking at everything under my hood. And noticed a wet spot under my master. So i pulled it and its leaking fluid past the piston seal. Haven't used the car enough to see a drop in the fluid levels.

So going to order a new master and it should fix it!

If it isn't one thing its another!

At least it's super easy to get at and replace. Be sure you bench bleed it before you install it. I'm glad you found the problem.

I just found brake fluid leaking from what I though was my master cylinder, but it just turned out to be the gasket under the cap.
