I have a brain fart, Im going to be doing my brakes this weekend can anyone tell me if the GXL's had 2 or 4 piston calipers on the rear? Dont remember seeing anything on the rears in here. I know the fronts have 4 pistons.

 

Rear calipers are all single piston.

 

The reason why im asking is Advance auto parts sell remanufactured 4 piston rear calipers for our mazda. Will they just bolt right on?

 

sounds sketchy... plus you don't need that much braking power in the back, remember it's mostly in the front. I'd stick with the stock single pistons

 

bump

 

This is true, It was just alittle wierd reading this:

http://www.partsamerica.com/ProductD...e=5003&PTSet=A

 

The 4-piston caliper system has a single-piston rear caliper that is different from the "standard "brake system. So, maybe what they are selling on that page is the rear calipers that go with the 4-piston caliper system? That would be my guess.

 

That link doesn't describe the rear caliper itself as 4-piston, it's referring to the rear caliper applicable to cars with 4-piston fronts. The upgraded rear caliper body would be wider as it fits a vented rotor (the base models brakes are solid rear rotors w/ different, narrower caliper body).

 

Brake Caliper: Rear Left Caliper With Pad; Coupe; With Hard Suspension; 4 Piston Caliper

Yea ok I see it now, so I would have to get those to match with my 4 piston calipers in the front? Thanks Told you a brain fart had something to do with it

 

Just get the one applicable to your rotors.

 

I have the 4 piston calipers on my GXL, so assuming the decription is right I will have to purchase them. I plan on getting new slotted/drilled rotors from ebay.
