Front right rotor hotter. Slight pull to right when braking

First post here guys. Been lurking for a while now.

I just replaced all brake components besides the booster and the hard lines. Used power stop complete kits front and rear. I’m getting a slight pull to the right when braking and that rotor reads hotter than the others. I installed an adjustable prop valve and did all the flaring myself. Brakes work good other than the issues I mentioned above. Think it’s possible there is a construction in the front left line causing the front right to work harder? Trying to get this sorted before I adjust the front and rear pressure so most of the load is on the front at the moment. Thanks for any insight or help as I am new to third gens.

Hi KnightG, welcome to TGO

I don't think your problem is on the left, my best guess is the caliper on the right is a bit tight or binds a bit and that is causing the increased temp (and grabbiness)

PS, please don't hate me for saying this, it's my own personal experience only, but, , , I have been burned once on "Powerstop" parts and now have no faith in the brand.

Seems like there's something wrong with the caliper. Aside from bleeding it again, I suppose you could pop it off and inspect the piston for signs of friction, actuate it in and out a bit to see if you can free up whatever's happening there.

It could also be a faulty part, I believe Powerstop sells remanufactured calipers so it's possible that one was just too far gone.

Did you replace the flex hoses in the front? Those are noted for getting constricted at the center mounting collar and holding pressure in the line.

Thanks guys. I didnt expect powerstop to be without flaws, the price was right for what I was doing. I remember having trouble getting the clips and pads installed on one of them. It was really tight.

I replaced all the flex hoses with braided so that’s not the issue.

I will take the caliper off and add some lube and check the piston. It seemed to be a little better today so maybe it just had to self adjust?

Here is a pic of the car. Put a 4th gen ls rear end and c5 wheels on it. Regret doing the wheels as I have quite a bit into it with spacers and tires. Can’t beat the price on the rear end though. Huge difference.
