    Pump was whining before failure, so I think the actual pump ( bearings) went bad. So, do I replace the whole mess? What about the accumulator and relays? I don't want to keep replacing the expensive pump.

    Thanks, John

Ok, your light WILL go out, and go back to normal once repaired, so don't fret.

Unless the pump was really loud (bad internals), you likely burned up the pressure switch (green thing on end of pump), which can be purchased in LA, USA; or through me, GreenDog Oregon (store name on Ebay US). These go out due to the pump running for an extended peroid of time, overheating the entire assembly, and allowing moisture into the pressure switch (Yes, they do go bad, and I have pictures of the inside of a bad one, full of brown muck). The reason this happens is bacause the nitrogen charge in the ABS accumulator (ball like canister attached to pump) has a limited life-span, and goes bad after about 7 years (Rave 2003). This means that the pump must run more often to accomidate braking, as it has no assist.

So, you can replace the Accumulator, and the pressure switch, and will likely be back in commission, after a proper bleeding, of course (directions for proper bleeding in Rave 2003 -CD available on ebay for appx $5)

Or, you could just replace the entire assy with a nkown good used part, and since the switch on the used part will likely be good, you can then just replace the ABS accumulator. The pressure switch is very hard to find, but I do have a couple of sources, here on the West Coast.

If you need further assistance or need a pressure switch (or parts), contact me through my ebay store, GreenDog Oregon. If you have trouble finding my store, just look for P38 and Classic parts, I'll be near the top of the store listings, as my prices are low, due to the low cost of rovers in the NW.

My 1996 Range Rover HSE ABS light went on and the brake pedal goes to the floor. Brakes were working fine prior to this. Once you pump the brakes; they work

are you losing brake fluid? you may just need to bleed the brakes if you bleed them and have the same thing happening, you are going to need a master cylinder, but first check around at all four calipers and around the brake booster and master cyl, for wetness this means theres a leak.

Brakes not engaging immediately.. need to be pumped

check the reservoir immediately. it apprears to me you have a leak. check for fluid on the ground and on the inside of each wheel. if you see no fluid and the reservoir is low, the master brake cylinder could be leaking into the brake vacuum booster.

Brake fluid transfer from Master pump to ABS pump

hi from uk if you are saying that the brake master cylinder reservoir fluid is falling in level? and that there is signes that fluid is leaking from the ABS hydraulic master cylinder ie fluid is leaking from the arpeture where the electrics wiring loom enters then there is probably one of the piston/valve seals leaking within abs assy ? or is leak from somewhere else? not had this problem before with fluid passing from abs assy resulting in reservoir losing fluid in this way?

Brake system

Hi, It sounds like the brakes need bleeding again, but just as your about to finish and all the air is out make sure the brake pedal is pulled up all the way before tightening the bleed screw.
You might need to bleed the whole system but if you still have the problem, then you will need to check for leaks and if none are found you will most likely need to replace the brake servo and will have to bleed the whole system again. This should solve your problem and if you have any problems or need me to answer any other questions, give me shout and will gladly assist you further.
