i understand that there is either vented discs or non vented discs in the rear, but is there a difference in the caliper between the 2? like the vented disc calipers are a bit wider to accommodate for the wider disc?



also...



the front discs... how do i remove them... lol... ive heated it up, ive sprayed penetrating lube on it, ive beat on it with a hammer... any other tricks for this... or just keep doing what im doing?

The front disks are held on by 2 + screws. they are a bitch to get out, a inpact screw driver works best( the kind you hit with a hammer and turns) or you can just drill them out. There is no differance in s4 5 lug rear calipers.

forgot to mention that i removed the screws in the front with ease... just having trouble removing the rusty disc





but is there a difference between the s4 4-lug rear calipers and s4 5-lug rear calipers?

Only help I can provide is to hit the rotor on oppisite sides to break it loose, I dont know about the 4 lug rear rotors sorry.

should be a random hole in the rotor, like 90 degrees from the screw hole.



find a bolt that fits and start tightening till the rotor pops off.

don't forget to check if the s5 caliper is for vented rear disk or solid rear

silver86

you sure? i know the rear discs had that little hole... but i didnt see/notice a hole like that on the front rotor...



the red is where the screws are located...

s5? i own 2 s4s... one is my parts car (which is gonna be sold to a friend of mine) and the other is my project car...



so does your statement mean that there is a difference between the calipers for vented rotors as compaired to non-vented rotors?



the reason i ask... is cause if i dont need to swap the rear calipers out... then i wont, and its one less thing i have to worry about...
