Hi everyone. I've looked through the archive and can't find any references to my issue, so here goes...
We bought a 2008 Grande Punto 1.9 M-Jet Sporting a few months ago when we probably should have walked away. However, we are where we are, and the latest - pretty troubling - issue concerns the brakes.
When you brake (at any speed - it's happened to me at around 50mph and to my wife at under 10), the nearside rear wheel locks with very light pressure on the pedal and before the ABS cuts in. This has the effect of sending the car sliding across to the left, which is quite unnerving. Not to say potentially lethal.
No warning lights are coming up on the dash and no codes on the diagnostics.
With the help of our local garage, we have so far tried changing all discs and pads (they needed it anyway), purging / bleeding the circuit, swapping tyres front to rear and side to side to see if wear was a factor. It's not, still always the nsr wheel locking.
And the latest thing we've tried is a new ABS pump to see if it was sending the wrong pressures to the different wheels. No joy.
We are reaching the end of our patience; the car was bought to be a courtesy car for our business and until this is definitively sorted, we can't allow customers to drive it.
Our next step is to change the nsr caliper to see if that helps, but it's a slim hope.
Does anyone have any bright ideas as to what might be causing the issue?
I feared a bent/cracked chassis, but apparently that's unlikely.
All constructive thoughts welcome!
