Question about 1997 Ford F250 SuperCab
I had a full brake job done on my 1997 f250 light duty including replacing the front rotors, calipers, pads, etc at a goodyear tire service. since that time the left front caliper will builds up pressure in the line and rubs the rotor causing excessive brake dust, loss of gas mileage, and pulls to the left. I opened bleed screw on left and released excess pressure and is fine for a while but slowly builds up again. have replaced caliper 3 times and still has same problem. Very noticeable difference in fuel economy. I have replaced the brake line from the calliper to the diverter valve as I was told the mechanic that did the brake job used vise grips to shut off the brake line while disconnected from caliper and damaged it causing brake fluid to build up pressure in line like a one way valve. This did not stop the problem. I suspect that he reused old fluid that was contaminated and has got a piece of contaminant in diverter valve that will not let it work properly letting fluid go back to master cylinder when you release the brake pedal. everyone I ask about this shakes their head and just suggests that I replace everything from the master cyl to the brake pads, this would be rather costly. any suggestions?
Hello i think you should have the system power bleed with a power bleeder theres a good chance the plunger in the proportioning valve is sticking if you have this truck power bleed it will push out the old fluid replacing with new usually if theres any type of contaminates especially oil ,or power stewering put into master by mistake it would swell any rubber piece to the point of a hard pedal and nothing working then you would have to replace everthing like your being told the only thing you could still use would be the lines wich would have to be cleaned with denature alcahol i would have it bleed in sequence firthest tire down to the closest to the master goodluck
