Re: Most new masters do not have the RPV in them anymore Posted by cougrnut on 7/24/2008, 5:13 am, in reply to "Most new masters do not have the RPV in them anymore" 68.34.170.124 for the 68-70 mustang cougar power disc brake master, which i use for my car that has 4 wheel disc, then how do you retain the residual pressure if the master is designed for drum rears? I was trying to tell a cougar friend who is switching to 4 wheel disc, that he can use his existing 69 cougar power disc master and just pull the rpv out of it. he wasn't getting what I was saying, so he asked for pictures. I was hoping someone might have pics of the procedure. Otherwise do you have any masters that you recommend that would require any fabbing of new lines, etc? thanks...sorry I couldn't make it to you birthday bash  Post an Intelligent Response

RPV Posted by bruce n. on 7/24/2008, 6:55 pm, in reply to "Not a picture BUT a good explaination" 76.79.85.71 If you look in the brake MC ports behind the cones you can sometimes see what looks like a bead made of brass, that's the r.v., if it's not there then there is no r.v. .  Post an Intelligent Response
