V7 STi pulls significantly to the left under heavy braking

[boon]

Subject says it all really... when braking heavily at highway speeds the car pulls very, very much to the left. ABS not kicking in. Under light-moderate braking it doesn't at all except sometimes when coming to a complete halt it will do a little shudder to the left.

Znoelli slotted+drilled rotors, Brembo pads, dunno how worn. I think they were relatively new when I got the car ~15000km ago. Brakes have been flushed and bled ~5000km ago.

Any ideas?

uneven braking surface... you night want to rebleed your brakes unless one of your seals is stuffed... its about $700 to get it reseal that is just for the part... there was someone in here selling the reseal kits for half that price here

Worn suspension joints or bushes at a guess

Get the calipers checked to make sure the pistons and slides are free

$700 to reseal a what?

ID say its a stuck piston or slider as said above . . A way I guess of checking is to have the wheel off the ground . Have some one standing on the brakes and see if you can turn the wheel with a power bar . . .

I'm getting it serviced next week so I'll get it checked out then. It recently got suspension changed so I have to wonder if it's a pinched/kinked brake line but I'm fairly sure it used to do it before they went in.

It just happened at a very unfortunate time... overtaking a wonderful highway-80-passing-lane-115'er when the police officer hiding in the bushes at the end of the passing lane turned his radar on.

I owe the guys at Beltronics a beer.

CAn get seals made WAY WAY cheaper than that - $100 per caliper

I'd be looking at the control arm bushes for movement & leakage if it's those liquid filled ones? it may be the wheel moving back with the heavy braking,

but then those were the first of the ones out with brembo's i think? so may also be the conditions it's been in & how they've been maintained & treated. could be caliper piston, dust boot damage, have you looked around for fluid leaks or posibly even cv grease,

maybe easier just to have it checked out if you're really unsure
