I'm having some problems with a jumpy brake pedal. The abs light has been coming on occasionally and the pedal occasionally goes to the floor. I have no fluid leaks and the resiviors are both full. Any ideas before I buy the wrong parts?

 

If ABS is constructed universally... your problem is in your ball bearing housing assembly. I am no expert but do you have a loud hum at higher speeds? The ABS sensor was in my housing assembly on my buick. That was my issue.

 

no hum at all. The car flies and is straight as an arrow with no sounds.
