The odds of 2 bad brake hoses are real slim. I would rebuild the calipers especially if there is no known history on them. Just something cheap and easy to do to get it out of mind. Bob
As Dane said above, be sure your pedal / pushrod mechanism is completely releasing the pressure in the system when the pedal is up. I had a similar problem on a '68 Ford p/u. I scratched my melon for months trying to figure out the problem. Turned out that the brake light switch mounted on the pedal arm was attached with a nut that was too thick, and wouldn't allow the pedal to completly release. A thinner nut from the hardware store solved everything.
i say the OP could take an axle and cut the brake lines off right at the calipers and his wheels would still drag.
I had this problem with an OT 71 SS Camaro. Calipers would stick causing the brakes to drag. Pulled the caliper apart, or tried to, and piston was covered in road grime, dirt and rust. And rubber boot was dry and stiff.
I had the same problem with the brakes that come with the g***er front axle kit from Speedway, when I put the calipers on, the brake pads were too thick to let them go over the discs. I called Speedways tech line and the guy told me to grind the pads down a little ( swear he did ), I ground them down but still had trouble when the brakes heated up. Very long story short, after chasing my tail for months, Changed pads for a good set, fixed.
Hey Harpboys....I certainly hope that you solve your brake dilema soon, but what I'd like to talk about is the picture in your avatar. Those burgers are killing me. I came home from hangin with the neighbor and took one look and realized I was starving. I can almost see the juice running down the side and the red onion??? My tombstone pizza just dinged...gotta go.
I had a similar problem with my stock daily driver, turned out the rubber brake lines from the calipers had started to break down inside, they looked fine on the outside and were not craked, but inside was a problem. Pressure went one way but would not release. Gradually got worse over time till the calipers would not release after I lifted off the brakes. I thought the calipers were stuck, new rubber lines, and she was cured. Hope this helps. How old are your lines?
im not saying anyones wrong or right here, but both caliper pistons seized at once, wouldnt be very common i wouldve thought, but can happen, i say release the bleeders and see, if same release the lines from calipers and see???
I've seen calipers ****ped up in pairs before from being taken from a donor car "as is" and not getting rebuilt along the way. Rebuilding the calipers and replacing the hoses would rule them out and not cost a ton either. Bob
yes totally agreed here bob, if there from wreck yards etc im 100% with you here , im a mechanic and run a shop here for my boss, the only time ive seen a seized caliper on a driver was from a clown that tried to push the piston in and ****ed it sideways whilst changing pads at home , other than that never, however what you say here makes total sense, i have seen second hand caliper pistons from yards that have huge corrosion and pitting which would jam in the caliper bores
