Hi,
I had my bias bar roll-pinned for the SVA and they checked it and passed my car last May, since then at least twice I've felt the the back end
lock and once start to turn under hard braking.
Could my bias have changed as the brakes have bedded in since SVA? Could something else have changed to cause this? I'm concerned because I know
it's bad to have the bias wrong and met a locostbuilder last weekend whose tiger spun because of bad bias.
Cheers,
Dan
Take the roll pins out and fit a bias adjuster.
Thats what i have done as brake bias can change if you fit different tyres and brake pads, add a bit of weight here and there and remove weight it
will all upset the front to rear bias
as above for various reasons yes it can
It really is just about impossible to set brake bias on rollers even using the official IVA method.
Bias must be be set on a good clean tarmac surface in dry conditions.
In practice two full turns to the front should be the most adjustment you should need to be on the safe side.
Put some EBC Green Stuff in the front...
More friction on the front will reduce pressure applied so stop the rears locking up so quick.
If that doesn't work uprate the front disc's to grooved and drilled...

grooved and drilled actually reduces brake power as there is less area of pad contact. However it is superior at higher temps.

As said, use Green Stuff pads and you won't go far wrong.
Thanks for the advice, I'll see if I can find some empty (wide) tarmac.
