So I have my 2000 F250 in the shop because I was feeling a funny vibration in my brake pedal. (isn't warped rotors, I know what that feels like). It also felt like the brakes were on, then would release a little, lengthening my stopping distance.


I took it to a small local shop and the guy said it sounds like the hydroboost. I told them to fix it. Next day, before they start to fix, they call and say they can't guarantee it's the hydroboost and may be the Power Steering pump.


My question is; is there a way to test it to know for sure which part is failing? How do I figure out which one is causing the problem?

 

Could be the antilock brake unit. I would take it to a Ford dealer to diagnose this problem

 

Sounds like the abs module. But as stated take to ford as they can access all the computer areas to get the true info. When at desk give them a detailed description of what is going on.
