Thanks for responding, how do you bleed air from the abs pump at the valve block?

Yes, the pump I purchased came as one unit pump, switch and accumulator already attached. I did swap the accumulator from the purchase pump unit with the accumulator already on the RR to try rule-out a bad accumulator. When that didn't solve the problem I put the accumulator back on the...

Yes, the pump stops when I remove the Relay. Sorry for the slow response to your question.

Thanks for responding! Yes, I changed RL-17 (New Relay) and I had the yellow abs relay (RL-2) CHECKED at a reliable auto motive shop, it checked-good.

Thanks, I'm entertaining all possibilities. Unsure what to do next?

I didn't disconnect or bother the brake pedal switch, I just rolled off the vacuum hose to see if there was a change. I then placed the vacuum hose back on the switch. Why would I need to reset the brake switch?

Thanks, so are you saying the brake pedal switch is not working properly or vacuum routing is wrong?

I will look for an enabled. Where do I connect it on the modulator? Thanks

Grrr thanks! I took it off the stands to take it for a drive to rest the pedal. When I started the RR I heard a kind of loud shhhhhh when I pressed the brake inside the car. I traced the shhhhh to the brake-pedal switch with the attached vacuum hose from the intake plenum. When I press the...

Thanks, it's an automatic 1996 RR 4.0 SE. I will bleed the system again today and let you know how it goes. Much appreciated!!!

How many times do you think I have to bleed the system to get rid of the air? Thanks

Sounds like I got air in the modulator (Master Cylinder Block). 1st I bought a Pressure Switch and swapped it out. 2nd I bought an abs pump with accumulator. 3rd I swapped out the old accumulator and bleed. 4th I changed out the abs pump and bled. 5th I put the purchased accumulator back on the...

Checked fluid levels and lights, okay. I'm trying to determine what's causing my pump to run. Do you think I still have air in the lines? How can I rule out the accumulator and master brake cylinder? There are no leaks anywhere vacuum or fluid. How do I check the abs pump connector wire? The...

Good morning or afternoon! First Thank You very much for replying. I let the pump run for up to 8 minutes or so. I make sure the reservoir stays full. It's an automatic. I haven't check the connector wire, I'm not good at electical but can learn. I searched the threads for about 2 hours last...

Hello all, I'm new to forum. I live in the United States -Michigan. I have a 1996 Range Rover 4.0 SE.. Had been sitting garage for 4 years. Got it started and it ran great.. Then the brakes stopped working as they should and the abs pump continues to run.. I've been trouble shooting for awhile...
