Brakes - Combination Valve
Has anyone ever rebuilt one of these? Does anyone sell original rebuilt?

Re: Brakes - Combination Valve
Early Classic sells these if this is what you are talking about:

Re: Brakes - Combination Valve
For some reason, the early classic one looks slightly different than the two I have. Has anybody ever tore one apart, cleaned it up, replaced the o-rings and reused? If you did, did it work correctly afterwards?
Greywolf, I do not believe there is a ChevyDuty. Last edited by stope4; 11-05-2007 at 03:37 PM. |

Re: Brakes - Combination Valve
I tore into one of the two of these I have this weekend. Suprisingly, these things are pretty simple. Looks like all you need are o-rings and a good cleaning to get this thing running smothly again. Does anyone have information on the proper sized o'rings. I went to O'Reilly's and tried to match them. They had o'rings that were the same overall diameter but the problem is the combination valve uses o'rings where the rubber itself is different diameters. Need some expert knowledge here.

Re: Brakes - Combination Valve
O.K., I had to hunt for the o'rings but I finally located the correect sizes. Does anyone know where I can find the v-cup seal that is located under the big bolt on the end of this contraption. I think it's mainly used as a dust seal but not 100% certain.

Re: Brakes - Combination Valve
You should make sure the seals are compatible with brake fluid.

Re: Brakes - Combination Valve
They are. The place I purchased them said they needed to be EP o-rings.
