Bad brake servo?

Post by triplewhite » Fri Jan 25, 2008 4:37 pm

My brake pedal is getting pretty close to the floor I have noticed recently... It doesn't feel like air in the system, and I had new calipers, disks (rotors), pads on the front, and new wheel cylinders, shoes, and drums (hubs?) on the back, along with new hand brake cables last spring so I don't suspect anything from those components.

A friend of mine had a similar issue some years ago, but I couldn't remember if it was a servo or master cylinder that was replaced.

If it is the servo, GermanAutoParts.com don't seem to list them... any ideas where to source a new one?

Thanks...

A bad servo can make your brakes "hard," but it won't make the pedal sink to the floor. I agree with Briano1234, this is the classic symptom of a master cylinder with bad internal piston seals.

New master cylinder fixed the problem. My brakes are amazing now, just like brand new... Thank you all!
