Rear Caliper Piston
 

Hello,

I have been doing a lot of reading on here and I have learned a great lot. I am currently trying to get a 1984 GSL up and running out of the two that were given to me. I am trying to rebuild the brakes and I cannot find the rear Caliper Pistons anywhere can someone help me out with this?? Also I am wondering how much coolant the engine and radiator will hold??

The FSM will help with a few things.

And, how can you not find the pistons? They should be right inside the caliper when you remove the brake pads.

also, http://rx7.foxed.ca has the service manuals.

I haven't seen a replacement rear piston, although rockauto may carry one. I would just get refurbished calipers.

I am guessing that he can't find new/replacement pistons since he said he was rebuilding the brakes. Could be wrong, though.

Can't help you much on locating new ones. Most people just get a new/rebuilt caliper. Check local autoparts stores (NAPA, Autozone, etc.) and check www.rockauto.com (they have good prices). For coolant, the systems holds 2 to 2.5 gallons total depending on year/engine. Since a 50/50 mix is usually recommended, I use 1 gallon of coolant and fill the rest with distilled water (about 1 gallon or so).

Y'know, I never read it that way. First thing that came to mind was not being able to locate them on the car.

Don't bother with a rebuilt kit, just get a whole new caliper. They don't cost that much. And, well worth it in the end, IMO.

Thanks For The Replys Guys

I am looking for new pistons because new calipers around here are 150 each for the rear and 60 each for the front. I will have a look around but if anyone knows please help me out.

They are about $60 USD at rockauto.com. They have one that is like $40, but they only have 1 left and it is only for 1 side (discontinued). If you order from rockauto, search on here first for a discount code. There is usually one for 10% off floating around on here.

Wow, that is expensive. I think www.rockauto.com is the only place that I've heard everyone laud with praise on their cheap prices.

You can also try www.partsamerica.com and see what they have for you.

For my SE, I paid about 45.00 for the fronts and about 85.00 for the rears. Well worth it. I bought these calipers a NAPA.

try checking black dragon as well. I think i bought a caliper from there but it may have been from rockauto. Way better to get new/refurb calipers imo. I got mine from rockauto for 35 a peice plus core deposit but i got that back when i shipped em my old ones

Before I order any calipers I am going to check the ones on the other car that I have. If these ones are gone too then I will probaly order from one of these retailers.

Jason

as well if u r set on new pistons, rock auto has them, and i believe black dragon auto also has them. from both places you can get a caliper repair kit as well. Includes some bolts and the boot and seals for the piston.

If you rebuild, id recommend you get new copper (squish i think) washers. They go where the brake lines connect to the caliper.

Neither of these places carry the rear piston. I cannot find them anywhere..I may phone the mazda dealer today and check but I will probaly be way over charged.

Jason

I never go to the dealer for such parts. They'll charge you 400% and get away with it. Just take our suggestions and get the whole caliper. Better in the long run to get an NIB item.

I am trying to do a budget build and I am only a student. I understand the concept of buying new ones but I would rather just do things myself.

Thanks For The Replys

Oh trust me, we're all basically in the same boat as you as far as financial constraints go.

But, the fact that finding a piston would be extremely hard for you, it'd be best to get a whole caliper is what we're suggesting, mostly from experience.

-If you don't have time to do it right, you must have time to do it over.
-The job must be done, and it must be done right.
-Spend the extra money now, before it costs you more in the long run.
-Good parts aren't cheap, and cheap parts aren't good.

I'm just saying this from experience. We'd like to make sure that your brakes are working just fine. We don't need your brakes failing and you can't stop safely.
