Proportioning valve rebuild kit
 

Is there a Proportioning valve rebuild kit or how can I check it to see if it is working. I have it off now. I have replaced everything on the brake system but this. 72 chevy c/10 front disk Chief mechanic for my 54Belair, 64Corvair, 72 C/10Fleetside and 2002Tahoe.

I have cleaned one before with I think mineral spirits.

Is there anything to it? Do you just take it apart and clean it up or is there something to be careful about when taking it apart?

I ran rubbing alcohol and then brake fluid through it will that be good enough or does it have to be taken apart?

Don't use mineral spirits, it will ruin the rubber parts. We took 2 old ones apart to try to get one to work for our 71. Not much luck. Best to buy a new one, I know they are expensive, but when you need to use the brakes, that is not the time to find out you saved $80. It's bad when they don't go, but it's worse when they don't stop.

I took the nut off the one end If I remember right I amy have use Sea Foam Cleaner in spray can or Mineral spirits. Mine did not work well until after I cleaned it out. My brakes in My truck are GREAT. I did all of this when I swapped to disc

I took mine all apart and cleaned it with bore brushes, pipe cleaners, and Q-tips - put it back together - never had another problem with my brakes

I went to NAPA and Autozone and they both said they don't sell them.

We got a new one from Classic parts of America. Guess they are more than I remembered.

is your brake warning light on

Re: Proportioning valve rebuild kit
 

If you take it apart and it's clean inside, just clean it out with some brake cleaner. Take the old o'rings to a place that distributes o'rings in Columbia. Tell them what the service is for and get some new ones. Use a little brake fluid on the new o'rings, slip them on, put back together and you should be good to go. Make sure the warning light pin matches up with the groove in the valve. If not, your warning light will go on.
