Hi Everyone,
Hoping that someone can help me and apologies if this is a bit of a long post - I will try to keep relevant.
I have a 2001 1.6 puma rally car (ST150 brakes all around). I have no ABS (module removed). Running AP coil overs.
Every so often, when I brake the car pulls quite aggressively to the left - as if the car is crabbing and sometimes even wobbling slightly too. There does not seem to be any rhyme or reason - happens at low speed under light braking and also heavy/ hard braking. It happens from cold or when brakes are hot. Usually, if I come off the brakes and reapply, the issue sorts itself out. If I keep pressing the pedal, the car becomes unstable and seems to lock the rear right - as if the rear is trying to overtake me.
This issue only happens under braking - car handles perfectly at speed.
I can do 2 special stages and it won’t happen - or I can tap the brakes as I leave my house and it can happen. I am really struggling to think what can be causing this - I have checked/ changed the following:
-Rebuilt callipers all around.
-Fitted mintex “fast road” pads all around
-Changed rear axle/ bushes
-Changed front control arms/ bushes
-Changed tie rods/ rod ends and realigned
- bled brakes multiple times
-Fitted bias valve for rear ( has no impact on this issue)
-full nut and bolt check
- hubs/ bearings all tight/ appear fine
- probably forgetting other things I have tried
Does anyone have any ideas/ suggestions as to what could be causing this? Again, this is intermittent and random ( I have tried and tried to recreate the issue but it’s impossible)
Any thoughts/ suggestions would be massively appreciated - running out of ideas!
