Re: break problems

I would replace all the rubber lines front and back and that should solve your problem!They are bad to dry and not work proper and its not really understandable .I promise you will see the difference.bleed the heck out of it through the boxes and wash them out so nothing is in the way. Just pm me if you got Qs

Re: break problems

sounds like prop valve to me BUT its still a good idea to replace rubber lines.
