Hello everyone... I could really do with some guidance again with my 2002 S Type 3.0...

I had a brake fluid leak, from the hose that connects into the rear left brake caliper. I therefore got a new hose and, whilst there, I thought I might as well replace all the pads around the car. Having done the pad and hose change, the dashboard now displays "Parkbrake Fault". I'm guessing I need to calibrate something - any suggestions or guidance very, very much welcome! (Not least because we're supposed to be going on holiday in the car on Tuesday and my Mrs is giving me one hell of a hard time about it!)

 

Just to add - the parkbrake (certainly at the calipers) at present is in the "off" position.

Also the old pads were wearing low, so the new ones are much bigger (calipers had to be wound basically right in) and so I'm guessing there is now too much travel on the parkbrake cable? But I don't know the procedure to calibrate/adjust - and I can't find the answer in the workshop manual!

 

I am fairly sure it can do it itself e.g. any time it goes through that Apply foot brake procedure.

Or you can wind the cable(s) back fully using battery power to the relevant power wires for the motor.

The module is fairly dumb. I believe it monitors the current being drawn and if large ("stall" current when an electric motor is unmoving despite being powered) it figures it's hit an end stop (fully on / off). I think it can issue an error if the time between end stops is too small (meaning things are stuck).

(Similar to the way the windows work when fully open/shut.)

You can probably make the motor work by lifting/depressing the paddle - I'd run the engine so there's more voltage & current available. Maybe need foot on brake?

 

Thanks for the reply. I've tried leaving the car running for a while and pushing the brake peddle. No joy, unfortunately. I know that the 2002 model still used cables to operate the calipers, so I'm guessing there is something somewhere that's not adjusting... but I've no idea what!

 

OP is your car a 2002 or a 2002.5, i.e. an X200 or an X202?

 

It's the late 2002 model - so the 2002.5.

Cheers!

 

I've managed to get the parkbrake fault resolved! I disconnected battery, gave it a charge, reconnected, started the car with foot on brake pedal and parkbrake lever pulled - car started and I heard the parkbrakes operate. However, I now have (as is often the way!) come across another issue... I now have a soft brake pedal! I will start a new thread though (sorry if that's the wrong thing to do).

 

Great to hear the park brake fault has been resolved. Just curious, how long did the car sit for this brake work? The fix apparently was to make sure the battery was fully charged. I'd like to add your results to this thread keeping track of what has worked for park brake fault messages, but it would be helpful to know how long the car was inactive:

Something to consider is you may have a slow drain still present, running down the battery while parked. If driven every day, or nearly so, the slow drain may not be obvious. But if the car sits for several days, the cumulative effect may be enough to cause trouble. More details here:

Hi Karl,
The car didn't sit for very long (by my usual standards at least) - no more than perhaps 4 days. But I'm a bugger for leaving the boot open or a door open, which has internal lights on etc. I can usually leave the car locked up for a week or more without driving and it will start no problems and not throw up any faults etc.
