Brakes on 1971 K20 Cheyenne - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just picked this up. We knew it needed work on the brakes. I'm the 3rd owner. It would would stop (soft), but it wouldn't lock up. The previous owner said he replaced the master cyclinder and other parts. The flex hoses are very old and showed their age. So I started to take them off. I was able to get them off the front calipers ( only one busted nuckle), but I can't get the connections to break at the steel line connections. I can hardly see the connections on the front let alone reach them. The rear is just being stubborn. The shoulders on gone on one of the flange nuts, so I'm down to using vise grips. I'm just about empty on the the 1st can of PB blaster. Any suggestions?
