Ok... here's the deal. For the past 6 months I have barely had a brake pedal. Mainly due to my master cylinder going bad, 3 MCs in 6 months. Anyway even when I put a new MC on I still can not get a brake. The shop I have taken it to will power bleed the brakes and get some pedal back but it's still nothing great. I'm really lost. Last night I was finishing the install of my 1 ton MC and Booster and when I tried to bleed the brakes there was no pedal (which was expected), however when I pumped the brakes with the rear nipple open the brake fluid barely came out of the nipple instead of squirting out. I'm assuming this is because of the booster being set up for Drums, but it still seems like it should get more pressure then that. I bled the brakes for an hour and I still have hardly any pedal. So far I have replaced the MC and Booster with 1 ton stuff, Front and Rear Disc brakes with 75 calipers in the rear and 85 calipers in the front. Front and Rear Stainless Steel Brake hoses. To my knowledge, the only thing I haven't replaced is the PV. I plan on replacing the PV with an adjustable one then having a straight shot to the front calipers. Is the PV on the front Crossmember where the ORD steering box brace bolts? If not can that little block go bad? I'm running out of things to replace and I desperately need to get this on the road again. Who sells an adjustable PV for the best price?
