Default parking brake questions

How does the parking brake work on the C4's? I know on the C3's and C5's it uses a drum style inside the rear rotor. Does the C4 use this same style?

the early c4's do , the later years do not. i don't believe the c5's use the drum type either, but i may be wrong.

I know my 94 they use a cam type lever that actually pinches the regular brakes to the rotors. Thing is I have to figure out how to adjust them as they are not straight forward by any means !

They are self-adjusting. Your parking brake mechanism might be sticky and preventing any adjustment. I just went throught this last weekend.

Remove the drivers seat for access to the parking brake. Remove the PB cover. You'll see the PB mechanism. Most likely it is full of debris and hard grease. You'll need to stuff many paper towels around the PB assembly and spray it down with parts cleaner. Relube with some white lithium grease and see if when you pull up on the PB, that it ratchets. You may have to take a pick and clean the gear teeth out so that the ratchet mechanism works.(mine had hard grease in the teeth that prevented it from ratcheting) After you've cleaned everything, pull up hard on the PB 3or4 times, and it should be self-adjusted. If not, you may need rear pads, or have a problem elsewhere. :cheers:

Does anyone have any pictures of this setup?

thanks
