Can anyone help?
Just bought a 2000 W 1.8 XEI 5 door Freelander with knowledge of it having a problem (it was cheap); intermittently, there's no brakes!
I was led to belive that it was the ABS modulator so bought a second hand one from Equicar and fitted it - only to find out it performs exactly the same way. I don't want to replace everything till it does work so here goes....
Every now and again, the brakes seem to fail - the brake pedal doesn't depress in the usual way (its hard and doesn't have much travel) and the're virtually no braking (although theres a small amount). There's also a sound which is similar to metal to metal contact of brakes.
I've checked that the servo works (by evacuating all the air with the engine off then starting the engine - the pedal sinks as the vacuum builds
The 3-amigos aren't present - although they do light up in the normal pre-check fashoin.
The ABS light goes out at 5-8MPH and stays out
The ABS functions properly most of the time (tried braking really hard in gravel and the pedal pulsates properly)
Diagnostics testing shows that the replaced ABS unit pump and solenoids work when triggerd.
Same testing shows that the speedo can be set to 100 & 200KMH by laptop with only the ignition on
Live data shows there's a signal going to the wheel sensors - but no signal coming back
A brake line to the ABS pump/modulator has been replaced at some time and I've traced it back to ensure it does go to the right (i.e correct) rear wheel
Live data can't pick up road speed.
At one stage, the speedo went dead (fixed by replacing a fuse)
The Auxiliary power point fuse kept popping till I disconnected it at the rear of the handbrake console (not related to above - I think)
We THINK the problem tends to occurr more often above about 20MPH
The brakes have been bled using a vacuum at the caliper/cylinder bleed nipple
Both rear wheel cylinders were leaking badly so were replaced with Lockheed items
A quick look at the ABS rings on the front driveshafts show them to be catching somewhere and becoming shiny in places - although not the full 360 degrees indicating perhaps some rust distorting them.
Similarly, the ABS sensors have begun to be worn away at their tips.
Can anyone help with a few questions;
1 Has anyone got a ready made answer (other then sell the car on)
2 Is there a free link to a URL for the ABS wiring diagram for this type of Freelander
3 Can anyone tell me if there's a primary wheel speed sensor (most german cars take it from the NSF)
Thanks - & you know if I coud help you out, I would!
