Check valve support.

Guest · Post Tue Jan 18, 2005 12:23 pm

Hi guys!!!

After a few months my brakes are not working properly- I have serviced all the brake calipers. Its a set of Black Diamond discs all round with jurid grade one and ATE blue brake fluid but my car braking is still the same as before after I did all that

and a few day ago I was just thinking I had better give it a try with a new "check valve support" I have bought it today and got it fitted...wow!!! now my brakes feel really good. so guys if your car braking feels lousy go get a new check valve support.

Thanks.

aha. it all makes sense now. thats just a one way valve isn't it. with the fooked one on did the engine run funny when u pressed the brakes(robbing vacuum from the manifold) or could you suck and blow through it? thats a good way of testing them?
