Yes. It was stopping just fine then one day my son drove it and said breaks went to floor to stop. Then I bought a pressure switch and changed it, same issue. Then I bought another abs pump with an accumulator and pressure switch. Before removing the original abs pump I just switched the...

Wammers, I am curious no one has answered this question, does the changing the abs pump ever require an analyzer/reprogrammed to bleed air out of the system?

Thanks to you all! I'm learning a lot. I'm going to do both especially since I still have the pump that was taken off in place of the one that I have now. I will check Ebay for another abs pump (Not sure how to choose a good one) and take apart the old one after work today.

Hey Thanks! So if I'm understanding you I should take the abs pump apart and clean it. Question if I clean it and that doesn't resolve my problem, should I try and have it rebuilt or find/buy another abs pump?

Correct! Everything is dry and no fluid leaks discovered. All the wheels are off no leaking cailpers or lines identified.

It goes right back-up. I watched with some else in the vehicle operating the ignition and helping with the bleeding.

I Thank you! The relay is brand new. The abs pump is used. I've tried 3 different Pressure Switches; the one that's already on the RR, I purchased one online and one with an entire unit (ABS-pump-accumulator-pressure switch). The probability of all these parts being faulty Seems unlikely...

Well I followed rave to the letter 2 times but when I get the last step "Turn on ignition and let the pump run until it stops accept it won't stop. Not sure what else to do. The only thing I come up with, is that a scanner is needed to open and close the valve in the pump. I did replace the abs...

Grrr Thanks for responding. The only thing noticed about fluid level is when pump is on fluid in reservoir goes down to near minimum and when ignition is turned off it goes back to maximum. The pump does keep running when ignition is on. Not sure what you mean by does switch go high or low or...

I will follow RAVE 'a instructions to the letter in the morning and I will let you know what happens. You are 5 hours ahead of me, so I will bleed around 10:00am my time should be 3:00pm your time. If you monitor your email I can follow up with you for additional advice. Thank you very much!!!

Hello all, I have two questions 1st- I'm want to purchase a power bleeder but I don't know the millimeter size of my brake resevoir "cap". Can someone let me know? (Is it 45mm, 42mm etc). I tried to measure but it depends on how you measure. 2nd- Is it possible that I need an analyzer/scanner to...
