Sounds like it could be a master cylinder or brake booster problem. When you pump the brake pedal while the car is on does it get harder each time? If not then your brake booster isn’t getting enough vacuum to build pressure to assist the brakes so check the vacuum lines. If it looks good then you may need to replace the booster.

I’ve recently replaced my brake booster and I’m still experiencing a VERY hard brake pedal. I’ve bled the brakes and tested the booster by holding down the brake pedal, then turning the engine on. The pedal dropped a bit when the engine turned over.

I’ve read that the pushrod length to pedal may need adjustment. (Which I did not do)

Can this be the case?

If so, how can I adjust the pushrod on the master cylinder and/or brake booster?

Thanks!

Hey spartanix! We installed the master cylinder and when we tryed bleeding it it never obtained pressure on the brake pedal, it still goes way down,what could we be doing wrong,i mean at times it obtained very little pressure, Is there lots of air in the lines or is there a sequense we didn’t follow. we’re overwhealmed with the fact that we bled every tire and couldn’t adjust them.

I replaced the booster and have replaced two master cylinders. The third master cyl. released more air on the bench bleed than the other two. The wheel lines bleed clean rr,fl,rl,rf according to the book and the pedal still goes to the floor almost. The car does stop no problem there but that pedal goes almost to the floor.It can’t be sucking air or there would be liquid all over the floor and ther is none! Just one more note I have also replaced the front pads and rear shoes not because I thought this would help but they were worn paper thin, the calipers work fine and the wheel cylinders were also replaced because they would stick on one side. I have bleed many brake systems over the years tahoes caravans broncos other hondas without such a problem but this one takes the cake!

Could be the brake booster needing replacement. Check the vacuum hoses that go to it as well. Usually you’d want to get a vacuum gauge and diagnose the brake booster before you replace it.

I have a 94 civic and have replaced the master cylinder after bleeding it prior to installation. The problem is that after bleeding the braking system the pedal still goes to the floor. I have done this twice, what can be wrong?

Hey spartanix, thanks for this guide it is very helpful. I was wondering if you could point me in the direction of a master cylinder installation guide. I just want to make sure I don’t miss any steps in the process when I replace my master cylinder because I am having the same problem as Alisha. Thanks in advance!
