Car pulls under braking

Hey guys, new to the forum. I searched around and didn't see a definitive answer. Just bought an 05 6spd, 45k miles. It needs a minor alignment and a few other little things but i absolutely love it.

The issue I'm having, The car drives fine, but under really hard braking, it pulls to the left. The car does need a slight alignment but the alignment pulls slightly to the right. The pads all look even, slides and brake hardware is all greased and good. Anyone have any ideas?

Get the alignment squared away first, then see what it does.

Wheels torqued properly? Wheels balanced correctly? PSI good? Wheel bearings OK? Bushings? Allignment?

The previous owner said he has replaced all the front busings on the car with poly. Wheels are balanced, the car has drag bags, I'm running 10psi in both bags. Tires are all set at 35 psi.

having a brake pull, could be suspension, alignment, tires and/or brakes.

for suspension, you could have something causing excess changes in camber,caster and/or toe. Tires to be pressure or a belt. Brakes could be a rotor/or caliper concern.

Get a alignment . Have the rotors checked and maybe turned downed a little.

Well i've been playing around with it more, and it only does it high speed (75mph+) and it does seem like the suspension shifts left when it does it, i'm thinking a caliper sticking or something jacked with the left side suspension. I'm taking it wednsday to get it aligned

Sounds like a ball joint or a bushing, again, go get an alignment. They will find whatever is wrong.
