Remanufactured Caliper: Normal vs Hard Suspension
 

There are few remanufacturers and they offer different part numbers for different suspensions (or referred to as different rotors: vented vs. non vented):

MAZDATRIX - FRONT: same P/N; REAR Different P/Ns
RAYBESTOS - FRONT: different P/Ns; REAR: different P/Ns

These are all the same:
CARDONE - FRONT: same P/N; FRONT: same P/N
ARI (ACEI) - FRONT: same P/N; FRONT: same P/N
BECK/ARNLY - FRONT: same P/N; FRONT: same P/N

Would vented rotors be much thicker that normal suspension non-vented rotor? And consequently, pads in non vented caliper would be rubbing against vented disc?

Also, any experiences with these brands?

Thanks,

Usually the way they these manufacturers distinguish between 4 piston calipers and single piston calipers on the FC is by using the hard suspension or soft suspension designation.

I have noticed that MAZDATRIX had two different part numbers for 86-92 rear single piston caliper: one P/N for vented and another P/N for the non-vented disc. However, only Raybestos has two P/Ns for them as well as for the front 4 piston calipers. All others do not.
So, if I get calipers from any source with single P/N - will there be a non-compatability issue?

Thanks,

I'm not sure I'm following your question, but the different p/n's for the vented and non-vent is because the vented rotors are thicker, therefore the caliper has to be wider at the pad "fingers". You need to get the correct p/n for the rotor you're using...

I think you already knew this, but I can't figure out exactly what you're asking...

Hi Wayne,
My basic question is: why most auto parts sellers specify only single P/N for both vented and non-vented rotor? And this applies to most of them. Only Raybestos has two P/Ns for them. If I was to get a caliper from a single P/N source - it might not fit, right?

ARI, Beck/Arnley (BA) , and Cardone do not have different P/Ns for vented and non-vented rotor calipers. Sellers on internet list the same ARI, Cardone and BA P/N for both "normal" (non-vented) and "hard" (vented) rotors. I got e-mail from BA advising they do NOT have seperate P/N for each rotor type! Mazdatrix has different P/N for raer only. They use sama P/N for the fronts.

If the vented rotors are wider - how come most remanufacturers do not know that??

Thanks,
