I just replaced brake pads all around with new brake cylinder, but the car pulls to the left when I brake. I thought it was alignment then I headed to the alignment shop for a alignment. The problem is still there. I already checked tire pressure and tires are brand new toyos. any insights??

 

Did you bleed the system at all four wheel cylinders?

 

did you grease your caliper pins? are any of your brake lines leaking? those are obvious reasons why your car pulls to one side when braking

 

right calipers probably seized/seizing
a leak would result in soft pedal. not pulling

 

What could cause the seizing??

 

slider pins not lubed, as mentioned. deterioration inside the caliper piston/cylinder
how did the right caliper piston push back when you did the brakes? did it push back fairly easy? or was it harder compared to the left?
did you use caliper slider pin lube? because it's specially formulated for high heat

 

I only lubed the bolts with the lubricant that came with the pads.

 

pretty sure that lube goes on the back of the pads. acts as a shim. i dunno. we don't use that junk at work.
you have to clean and lube, with slider pin lube, the slider pins. not bolts.
have a good look at the pins too. make sure they're nice and smooth and not corroded. if they are, wire brush them off. also, use some anti-seize on the spots that the pad rides on the caliper.

i think you should pull it all apart and recheck your work. pay close attention to the right side

 

Thx for your input!

 

tbh, maybe that stuff they give you with the pads is slider lube. i really don't know. we use our own stuff at work, so i just toss it.
what did the package say on it?

 

it said brake components lubricant.

 

oh ok. yea that should be slider lube.
something aint right though. did you take it back apart and recheck yet?

 

I typically toss any packet of brake lube that comes with pads as well. Only use copper anti-sieze on the part of the pad that sits on the shims. Not the back of the pad that the caliper piston touches. I use silicone paste for the sliders because it doesn't dry out and gum up like anti -sieze or typical brake grease.

 

So you say that it's not an alignment issue...

Before you press the brake pedal, as you drive down a straight and quiet road, do you hear any sound or noise?

Without braking, if you let go of the steering wheel, does the car drift to the left?

As you accelerate past 35 mph, do you hear a swelling, roaring sound?

If you've got about 150,000 miles on the wheel bearings, the passenger side bearing could be on its way out, causing you to veer to the left.

 

yup. copa-slip on the pad riding area, silicon lube on the sliders, and we like to spray crc anti squeal at the back of the pad, just for insurance.
