I just did the complete drum to disc rear brake conversion. I Have a question to anyone who has done this before. I got a rear s/s braided #2 lbs. check valve hose. I can not find where it goes. I assume it replaces the vent hose??? but the block provided doesn't match at all and it seems not quite rite. The instructions with the product is pretty crappy and no pictures to illustrate where it goes. So all is clear why i bought the conversion, is that my rear drums didn't brake properly no matter how often i adjusted them. I literally replaced the front pads 15 times and the shoes are original.!!! any info on this hose would be truly appreciated.
