Pads are same for 525 & 540. The difference is the thickness of the rotors, 22mm. (525, 530, 535) v 28 mm. (540) A thicker rotor with better heat dissipation for heavier 540. Worth noting that the ~ just as heavy 530(V-8) has the smaller brakes
The #s on the caliper casting indicate bore size, 60mm / rotor thickness, 22 or 28 / rotor diameter, 302mm
I wondered what the hell you meant when saying the ones you got were too small.
As long as the mounting bracket and rotors are appropriate you can switch one size for the other. There is no benefit to this aside better resistance to fading with repeated stops. Braking performance is same, the 540 brakes will just take longer to overheat with repeated hard use.

If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue
Well brakes are all finished up. To my disappointment, the car is still pulling right. I lifted the fronts and both sides spin about the same.( which isn’t much). Given I still need an alignment. Im kind of at a loss here. Im going to flip flop wheels tomorrow.

I mean I replaced the tie rods and center drag link and adjusted the tie rods by eye so Im sure they are pretty far off. But despite changing everything the pull to right still has the same force it did at the beginning, if that makes sense. It didn’t decrease or anything.
Im pretty sure they are bled properly! Thank you for the offer, Ill keep it in mind though.
As of now, one thing that came to mind is I replaced my left front wheel bearing/ hub a couple months ago. But Im not sure that would cause such an imbalance.
Does it pull without braking? Rotated tires?
Yes it pulls without touching brakes. I take back my initial title name, under braking it remains the same. Braking does not make it worse. And Im pretty busy this week. Won’t get the chance to rotate tires till the weekend. IMG_0523.jpg
I noticed my right caliper looks like this. Notice on left side the darker tint to it. I bedded the new pads. Im not sure what this means.
Ughh, stupid me chasing problems when the simplest diagnosis, which I was told to do early on, ended up being the culprit. I swapped my front tires and what do ya know, car pulled left. Took wheel back off and noticed that when sitting it up and rolling it was extremely tilted towards face of wheels. Almost like it needs 3 pounds of weights on the inner part of barrel. Im not sure what the hell is wrong with it but as a temporary fix I threw it onto the back and voila, no more pulling. For needing an alignment the car drives pretty damn straight! I have new wheels im putting on in coming weeks so Im not worried about it.
Sometimes it's only after years of stupid tail-chasing (not that kind...) that a mechanic - this one, anyway - gets good at implementing Occam's Razor. Live and learn. Glad you found the problem.
What I'm picturing as you describe that wheel is something I would not mount anywhere on the car. If you drive on it at all, be slow and extra-careful with that wobbly WTF on.
