Brake Drag problem
My truck(1992 F350 7.3 CREW CAB DUALLY) seems to have a left rear brake drag problem,I feel a slight drag /vibration coming from the left rear. I smell brakes,when I come off the highway.new shoes,new wheel cylinders.I adjusted them twice but still the same problem.Also when I am go in reverse.I get a hard pedal but it barely stops no matter how hard I push.Anyone have this problem.I also replaced the RABS module,and ABS sensor.The (ABS) light will stay on for a minute or so after I start the truck but then goes away.If I go foward its stops good? Any ideas?

I am baffled ? I am gonna replace the return springs.It was 20.00 for the set and the cable.I figured the truck is a 1992 and maybe they are starting to give.The brakes bleed fine and the truck stops fine but after a bit I get that brake smell just from that left rear.Never thought about the hose.I don't want to open the system up again for no reason.

Did you turn the drums? Could be a warped drum as well. Check the clearance on the shoes and turn it a few times to see if it sticks in only one spot. I second the new hardware kit. Springs can lose their strength over time and when heated up. Then when you stretch them extra to replace the shoes that could be the end of their useful life.
The reverse part says something isn't right. I'm going to 2nd Lazy K's thought on checking the shoes.

1 thing I have seen is the side of the shoe wearing a goove in the backing plate. When the new shoe would drop into it it would cause it to bind. I would assume you would have noticed that when rebuilding though.

Well I figured it out !!! I took the drums off and Cracked shoes !! Primary and secondary.The secondary had about 2-3 inches missing.The primary had a few chunks.After looking at the drums I need new ones !!! 100.00 for drums and 45.00 for shoes.I will have the drums by Monday !! Of course I take the new shoes home only to pull them out of the box and find that one is cracked !!! That was the brake smell.There were pieces wedged against the drum causing the smell.The E-Brake does not bind.I applied it twice and it applied and released both times with the spring collapsing and expanding.I replaced the shoes about two years ago.I am still baffled.I did have the drums cut and remember the guy telling me they were close to the max.Oh well hopefull this will solve my problem.

I checked it last night.The coating seems to still be on the cable.I released and engage it witht he drums off.It seemed to work and not stick.I am hoping it was the drum being thin and possibly out of round.I had the brakes bleed by a local repair shop.The guy said he adjusted them as well.Thats when the problem started.I am thinking he overtightened the left side and that caused the drum to hang/overheat and possibly warp the thin drum which caused a chain reaction. .After inspecting the drums,they had about 1/8 meat left.
