question on brakes on 1982 320is

[2002jm]

I just got my 82 320is in the shop and started taking it apart to do some work on the brakes. They seem a little soft in the pedel.
I noticed the front brakes have vented rotors and with stock wheels they have 10mm spacers. The brakes are bmw ATE r57 calipers.
According to the search I did, these are early e21 and 323i calipers. Does that seem correct to you guys/gals that know more than me about brakes?
Noticed on the passenger side it is really hard to turn the rotor. Looks like the brake pads are not disengaging; or hanging up. Is there any easy fix for this problem??
thanks,

You're right about early E21s and 323i's having vented rotors. It's a common bolt on mod for all e21s. If your calipers are sticking you can rebuild or replace em.

When I bought my E21 both front calipers were seized. It's not too hard to rebuild them.

Thanks for the reply, might just try to rebuild them.

more precisely only the 1977 320i and all 323's came with vented disks.

So if I want to replace the vented rotors on my 82, I need to get the 77 320i?

Yes. My '77 has vented rotors. Just order the '77 parts. The calipers have a spacer in them to accomidate the extra width.

Excellent; 77 pads and rotors it is.
