having trouble changing front brakes

[bmwm42]

alright so changing brakes isnt nothing new to me, however this problem is. my front discs are vented and have girling calipers, im in the process of replacing the pads and rotors using pagid brake pads brembo rotors the fucking problem im having is the they wont go on. The brake pads are hella thick and that combined with the thickness of the rotor exceeds the space available for the caliper wtf is going on. Any suggestions anyone btw im using all stock replacement stuff.

You are remembering to compress the brake caliper pistons right? If you have not then they are adjusted for the worn down pads and will not allow enough room for the new pads to fit over the brake disc.
Pictures?

^ I was thinking the same thing. You have to pust the piston all the way back to install them, even then, it is a tight fit. They make a tool for this or you can use a C clamp or a large channel lock type set of pliers.

Yea grab a big C clamp and compress that piston

[bmwm42]

they are compressed as far back as the go. i also have spare calipers that i have tried them on and the pads combined with the rotors are to thick to fit. i just replaced my rears with no problems

[deutschman]

then you have the wrong brake pads or rotors. where did you get the pads?

This...

But if this is true....

then you have the wrong brake pads or rotors. where did you get the pads?

Then I agree with this.

using brembo rotors 34111160915 and pagid brake pads 34-11-1-162-481-M73 i ordered my shit thru bma

verify the part numbers on the boxes from your order, and the part number from part to box. I had a similar situ YEARS ago, and I got some random vw rotors in an e30 box (brembo too). GL

This actually happened to me just recently.

[bmwm42]

the rotors and pads are matching the pnsi think the problem is with the pads that they are to thick im having a 1/8 or so problem with clearance.

[Matt-B]

i always think the pads are to big, but manage to get them in, what pad are you putting in first?

and are pads different for ate and girling?


mine are girling

[bmwm42]

mine are girling pads are the same for all e30s im putting them both on the carrier then trying to put the caliper on. ive tried putting them on the caliper and then putting them on the rotor shit isnt happening.

[Matt-B]

piston all the way compressed, take your brake fluid cap off to, so it can rise etc, not usre if it matters...when i compressed my piston, i thought i was done, but it went down more, and i slid 1 pad in 1 side, and did the other side

[bmwm42]

yup cap is off i have tried it with a spare caliper that i have compressed all the way and shit isnt going in
