Thread: No brakes

From memory, a 93 Rangie with ABS doesn't have a vacuum booster. It uses a pump and a nitrogen filled pressure accumulator to provide the braking force. I have had to replace a pump in the past, quite expensive and the bleed procedure is very long winded. You would need a manual to do it properly, I can't recall off the top of my head how it went.

In summary,

1: ABS Pump,
2: Under the bonnet son,
3: You can't.

The cheapest fix is to fit standard vacuum brakes from an earlier RR.

Look here for info on your brakes - same procedure as P38A.

Yours has a remote accumulator whereas the P38A has its attached to the pump.

Check that the fuse to the pump is OK. If the puimp is running, how long does it take to get brake pressure? Anything ocver 45 seconds probably indicates a failing accumulator.

ABS pump under bonnet drivers side up by firewall,
turn ign on u should here pump spin up (no noise bad)
check all elect con into pump.

depending on whats wrong can be a fairly cheep fix but on the others side could be dam expensive

Good luck, yabbie. I don't know if this helps but I have a thread running about a similar prob with my 93 disco, titled 'leaky brakes'.

cheers, GQ

Looked at the fuses and low and behold the fuse for the pump is blown.

Didn't even know the damm thing had fuses for the brake system.

Off to get the new on tomorrow hopefully thats all it is!!!

Cheers to everyone who helped out with the info.

Not to rain on your parade Ron but methinks this may be illegal, by pulling the ABS out of the vehicle your removing a safety feature, or have I latched onto the concept incorrectly....

did you meant replace the whole abs box and dice from the master cylnder down and replace with a vaccum boosted unit?

or add a vaccum booster in addition to whats allready in there?

Oh, very likely illegal. I know that complete removal of the ABS and replacement with the braking system from an earlier model is relatively common in the USA.

But in all likelihood, no one would ever know because it would look like any other earlier model RR.

you should have some spare fuses in the fusebox behind the gear lever.....
