abs+tc+ hand break lights come on

today, while i'm driving my p38 4.6 1997, the tc and abs and the hand break lights come on , and the break became spongy! any idea please?? regards!

Accumulator gone or the hydraulic pump, assuming that the system has fluid in it and no leaks.

I had same on mine 12 months ago, pump switch was shot, ended up getting a good second hand unit, pump, switch and accumulator (not cheap) but cheaper than the main dealers!

ok, so i have to go tomorrow and search for a second hand unit! thanks for your help!

I really wouldn't suggest it, especially as where you are I imagine its not easy finding parts and if you do a job once you don't want to do it again. I would also strongly suggest you change the accumulator regardless. They were designed for a service life of about 8 years. People talk about Range Rover unreliability but most accumulators have successfully worked for 12 years and more. Far beyond their service life. A new genuine one can be had for about a 100 pounds if you look around and once changed it will outlast your car. A second hand one on the other hand may already be reaching the end of its life.

Other than that, as Datatek has subtly hinted, check for leaks or trapped air before you do anything else. Once that's done check all the brake lines for kinks and corrosion. Perhaps change out the brake fluid, look for any discolouration or debris. Bleed the system EXACTLY according to Rave. Bleed it again. Get your wife or girlfriend to help, tell her its a wonderful toning exercise for her thighs!

Its possible to remove just the pump and run it. While they don't officially do parts I was able to refurbish mine, having the motor re-wound and replacing the carbon brushes (which I had to bodge as the wire comes out the side and most brushes you find will have the wire straight out the back. I found a pair with the right design but much larger so had to cut to size).

Edit. Just saw that yours is the same year as mine. That means two-wheel TCS. There are some scary threads out there (one by me!) about bits in the ABS modulator breaking apart. With a little more experience I can now say that its not a very common fault but doesn't hurt to keep in mind. The other thing is that at least on ours the ABS and TCS are basically the same system controlled from one ECU and depend on information from the ABS sensors in each wheel. So check your sensors, remove them, clean them, use contact cleaner on the connectors (not the sensors!) and when you re-seat them make sure to push them all the way home. One of the problems in our model is that they tend to "float" up a little in their docks and its a good habit once a week to just stick a thumb on and push hard to make sure that they are seated.

Had the same problem 2 days ago, turned out needed new pads all round, replaced all the pads, job done all warning lights back to normal.
