I just bought this truck. It has disc brakes on the front and drum brakes on the rear. When I brought it home, the brake light was on and the right front brake was dragging. I replaced the front calipers, hoses & pads. I bled out the air, and all looked fine. Today I was driving it around, and the …

you did ever thing i would have done. know i would check the lines running to the back of the truck and also check the wheel cynders make sure they our dry.

if every thing else checks out good i would think its time for a master cylinder

OK, I checked the brake lines and they look fine. The rear drums are dry except where a little fluid spilled when I bled them. The fluid in the system is amber in color and a bit milky, so I think new fluid is a good idea. I think I’ll go ahead with a new master cylinder too. What do you recommend …

Just put the new master cylinder on after you bench bleed it and start with rt rear and bleed it then lt rear then rt front then lt front when you get done you will have all the old fluid. Just as you bleed each bleeder make sure clean fluid is coming out.

Thanks! I followed your instructions and my brakes are working famously! Jim

Replace the master cylinder. Then re-bleed the brakes. I would bleed the how system to get out the old fluid. Also check the rear brakes for leaks. I don’t think you will find any. This sounds like a classic master cylinder failure.
