Brakes with suicidal intentions
What is the cause that makes the car, when braking at speeds above 80/100kms/h, from time to time (not always, actually it is rarely) beastly and suddenly pull to the left?
The brakes have been bleded this weekend and the problem persists.
There are no loose wheel nuts, brake pads are recent in all brakes and discs are in good shape
Car is a '90 Turbo without vented front discs
Thanks in advance

I would say, this might have something to do with the steering mechanism adjusments! That's usual way to test it: Drive the car, remove hands from steering wheel and break. If it pulls to any direction, you should get you're steering geometry checked/adjusted.
But thinking about it again, it really shouldnt do it, while you're having your hands at the steering wheel... Have you checked the brake pipes for any leakage?

I allready tried a steering allignment and it isn't that.
Pipes do not have any leakage.
Today I've made 5kms without braking and in the end I found the left front disk brake to be very hot. So it seems that this caliper is not releasing as it should and is allways braking a bit.
Wich is strange because front calipers have allready been exchanged a week ago in order to try to resolve the brake problem, but does not make difference.

sounds to me like you have a warped disk, or the hub is shot, try new disks, if this doesnt help replace the front hubs. if it still pulss theres somthing amiss elsewhere.

Hi
The discs have been "corrected" (don't know the exact word in English), exactly to erase any kind of "warped" (fledged).
Now... maybe this service have not been done correctly as I haven't driven the car before it.
Can it be the main brake pump?

hoses
this is a good point but if the pressure was still there then the pads would stop the disk from spinning
i park mine on a hill and it rolls thus proving the pressure is being released
so i sat on a hill with my brakes on no hand break let off the brakes and it rolled instantly correct me if im erong but proving pressure is being released instantly
i tried this numoruse times and it rolled in a straight line as well
so i have replaced the lower arm bushes on both sides and problem has gone it dosent pull either witch way anymore
hope this helps
