Something doesn't sound right here. If you are using disc brakes you should use a MC for disc brakes. If you are not using disc brakes you don't need a proportioning valve. ...but using a MC for non-disc with a purporting valve?

Short line was from same and a little tricky to bend. Mounted the prop valve in same location as old one.
