ok, got these with a bunch of other stuff off a 94 LT1 z28. I got the complete rear with PBR brakes, so I don't know if these are front calipers or from something else. I want to do a brake upgrade to the front of my 91- so wondering if I can use these easily with some other kit parts. Any help in ID would be great- searched these numbers but haven't found a good answer yet.

 

lt1 cars have the same front brakes as we do. those are pbr's, and if they are 1 piston, they are rear calipers, they will not work on the front.

 

Just a quick FYI. 84-5ish corvettes had 1 piston front PBR calipers.

If the OP could get a pic thats closer of the caliper. Please post a pic of the whole caliper. that would b very helpful.

 

here is a pic of them. let me know what you think. i am trying to figure out what i want to do for a front upgrade- sounds like it will be hard to get stuff from Ed these days. i think i will need a 1le valve though- gonna use my 4th gen rear with 12" rotors and pbr calipers.

 

Those are the very early (84-??) corvette single piston caliper..

 

ok, so not worth too much in my effort to swap in some bigger front brakes- right? they are in the toolbox on my trailer- which is in another state right now- so i wasn't sure about single or dual piston and couldn't go look- just had these pics already taken. thanks for the help. maybe Ed will answer my email about some LS1 brakes

 

They will work but Im not sure if the mount is the same as the more common calipers..
Any chance of getting a pic of them flipped to see the side with the pads on it??

 

ttop is correct, they are 84 vette calipers...in other words...junk

 

Twin_Turbo in a way there not junk cuse there lighter then the iron ones i would tak alum any day over iron let me know what you do with them dont just toss them

 

ever driven an 84 vette? I owned a Z51, the stock JL9 calipers on later years don't brake worth a damn, the J55s are decent/good. These...they are just terrible.

 

From the pictures they appear to be cast iron. Could be wrong, but... just saying.

They are alu, single piston vs dual on the later years

 

If these are junk then what replacement calipers are available. Thks
