I recently purchased a 1991 non-turbo model. The previous owner swapped out the front calipers with the 4 piston calipers from a TII model.

I'm currently in the process of purchasing new pads for my S5. According to the Hawk website, there are two different part numbers for the S5 rear caliper. I need your help to ensure that I'm buying the right pads for my car. Below are pictures taken by the previous owner when he had swapped out the calipers, so these are the actual calipers on my car. Please take a look at the pictures and let me know if the rear caliper is from a TII or N/A model. Is there even a difference between the two? Thanks for your help.

 

look at your rear brake disc, if they are vented *i think your rear calipers are vented because of the grooves*, than you would be considered TII rear brake pads. If your rear brake rotor is not vented, than it would be NA.

 

The current rotors are cross drilled, but I plan on running brembo blanks. Would that be possible? If so, would I be running TII or N/A pads?

 

i meant look at how thick they are, if they are very thin, than they are NA, if they are vented than they are turbo

here is vented

 

Watch me flash mad money in the first pic, My S5 TII Rear calipers, hope the pic help->





Ya thats a dirty keyboard but it`s sitting in my garage :P

 

NA models that have 4 pot front will get Vented disc for the rear. otherwise, its solid disc.

you said the previous owner swap the front, so I guess the rear is still using solid.

buuuuut ! its not hard to change that, just look for parts out, a lot of people selling vented rear calipers

 

I didn't know that. So I guess I got a t2 brake system on my vert. But I'm putting evo brakes on it anyways yee

 

I just checked... and my rear rotors are vented. Thanks, Hypertek.

 

The only FC that didn't have 4 piston fronts and vented rears is the S4 SE base model. Also the only one that is 4 lug.

They are all the same other than that. Even FD front calipers are the same as the FC 4 pots! Bolt right up as well, just a little different in the looks department. On the other hand FD rears don't work.

 

Check your resources/FAQ's again.

 

well i have a 90 base model with solid rear rotors,and a 91 full jam with vented, so s5 do come with solid rears

 

Some S5 came with single piston fronts also, e.g GTU

 

Those rear calipers look like the ones on my vert, same with the fronts.

I believe the vert (correct me if I am wrong) came with the same calipers and discs that the turbo did.

 

Read the FAQ please ...

 

Sorry for the mis-info. That's what I get for posting without checking first! A lesson in people to use the search button or FAQ.

 

Five lug hubs and vented rears would mean the car has the TII/GXL/Sport package brakes, regardless of S4/S5. Which on the Hawk site might just be listed as TII. It is possible, though unlikely, that the prev owner who converted the fronts to 4 pot could have left the unvented, 4-lug rears on, but that would be unlikely, and retarded, since it would mean mixing 4 lug and 5 lug rims.

 

You need to stop with the "Turbo Brakes are vented the N/a brakes are not vented" routine.

The proper terminology is hard suspension=vented rear/4 pot front and normal suspension= solid rear/single pot front.

A pretty close way to tell:

Hard suspension=Turbo, Vert in all years and anything with 5 lug wheels in 86-88 had vented rear and 4 pot fronts. Not sure about the S5 GXL is hard or normal.

Normal suspension=Anything with 4 lug wheels in 86-88 and anything 89-92 that is *not* Turbo, or Vert. There might be a couple of exceptions, but I think this covers most of it.


The FAQ seems to be missing some old information on these issues?

 

For the first question- the pads are the same regardless of the rotor width. I just did a 5-lug swap and the rear pads were exactly the same for the vented and solid rotors.
