Hello All,

I have recently had the brake pads replaced on my Pajero (with original spare parts) and the ABS has gone haywire! First off, the ABS light on the dashboard started coming on randomly. Now, I can hear some sort of whirring motor going off most of the time when driving. Noise appears to originate from around the passenger-side dashboard (this is a LHD Pajero, originally imported from Germany).

When there is no noise, the brakes work fine. When there is noise, the brake pedal will not push down all the way, and makes loud crunching sounds when I do manage to push it down. If I push down two or three times, I can usually get the pedal to fully depress. In terms of braking, you can get the car to stop, but it feels like the pads are engaging and disengaging repeatedly in a less than optimal fashion, with lots of crunch.

I am concerned that this is a safety issue and would like to know what to tell the mechanics. I am in Madagascar so the odds of getting proper diagnostics done are very slim!

Cheers,

Oz

Sounds suspiciously like the hydraulic brake booster is faulty and they are very expensive, they did a recall on them so check with Mitsubishi and check if your model was done.

I think there can be an ABS problem induced if the caliper pistons are wound backwards to fit new pads without loosening a bleed nipple, I've read that several times on here.

Also there is a diagnostic procedure you can do yourself with the fault code(s) being displayed in a series of flashes via the ABS light, I did this years ago on an Exceed with ABS and the fault was flashed out as the G-sensor below the centre console. I'll try and find the procedure.

My current SWB has ABS and I may possibly be breaking it if you need some impossible to source components, not sure about shipping to Madagascar though.

I remember doing the LED thing now reading Emax's link, it wasn't the ABS light flashing out the fault codes, but I did find these old scans from the service manual if it helps. I think it's all covered in the thread Emax linked though.

The 60A fuse on the front battery positive terminal is the ABS power feed if you wanted it disconnected, it's failsafe without power naturally.
