check these out and tell me if you can tell if they are for disk brakes or drum...the guy siad that he wasnt sure.

 

and another

 

i need to know if the booster and PV is for disk

 

ttt

 

I dont think there is anyone who can tell from looking at the pics, the disc and drum prop valves and master cylinders look identical from the outside. u can however use a drum mc in a disc car tho, just make sure the prop valve is correct. there should be numbers stamped onto it.

 

It's impossible to identify them by looking at them. The differences are all on the inside.

 

what would the numbers be? i was told this was stamped on one of them # NB 31KH 094 7

the pictures above, the guy told me that he believs the car was origanily drum brakes. but was swaped over to be disk brakes. so i dont know if the booster or any of that was changed. the porprtioning valve(i think thats the same as a "combination valve" according to my haynes) looks new. but i dont know if that has anything to do with rear disk brakes.

 

What year is that car?

 

good question,, ill have to ask

 

Broadcast Code NB Prop valve is for 4 wheel disk J65. so yes it is for 4 wheel disk. as for the car is will have to be and early 89' or older. since on the later models they changed the thread sizes from (1.0m to 1.5m) on the prop valves.

 

the car in the picture is a 88 firebird.
