Looking for a 4 wheel disc brake prop valve from a 90-92 Camaro or Firebird

 

Ive got one.... $25 shipped

 

What did it come out of and is it for a 4 wheel disc car?

 

I have both... the pre pbr calipers use a 4 wheel disc comb valve which I have, the aluminum pbrs actually used the same as drums and I have 1 of those too

 

Are you sure about the pbr calipers using the same one as drums?That doesnt sound right.

 

the difference in the 91-92 combo valve between drum and disc is so tiny youll never know, alot of guys have keept the drum combo valve and the rear pads are wearing at 60-70% to the front. Gm does have to seperate combo valves listed but I talked to a GM tech whose a thirdgen buff a couple of months ago about switching mine, he told me about the 89 cut off for the course thread combo valves and told me to not waste my time or money for the tiny tiny bit of difference on a 91-92 combo valve.....

 

Well here is my dilemma.I have an 89 vert and just swapped the drum rear with a pbr disc rear from an 89 formula.I havent checked the brake lines so im not sure which thread style I have.I grabbed a disc/disc prop valve from a junkyard 86 T/A but was looking for a newer 90-92 style one just in case my lines have the different threads so I wont get stuck

 

Keep me posted,, if you need a 91 prop let me know.

 

gm still sells these for the 4th gens, i believe they will work on thirdgens. a guy here in town did it to his 91 rs. id check into it because u can get em brand new for like 50 bucks.

 

just fyi they dont go bad, but the can be mis threaded

 

yeah but why pay 30 for used when 20 more bucks gets u knew from gm???

 

$25 savings and not having to leave my house means alot to me... but Iam cheap and lazy..lol

 

HAHA i hear ya!

 

So if the pbr disc brakes use the same valve as rear drums would I even have to swap the valve since I have a disc/drum valve in there now?

 

I know sofakingdom didnt switch his and his brake wear is were it should be... 60-70% wear on the back compared to the front.
