Hello. I drove my 52 f6 and the rear brakes got tight and started smoking . When I cracked the bleader at the cylinder, fluid under pressure squirted out. Going to go thru the minor and major adjustment and bleed them again. Making sure the cylinders are free. Is their something like a check valve I'm missing? Any thing I should know to look for.

 

Just a SWAG as I'm not familiar with the F6 brake system in particular- but that's a classic symptom of collapsed flex lines...If the rubber in the flex line is old and weak- you can apply pressure through it but it collapses when pressure is off and keeps the brakes on.

 

Does the truck have a hydroboost?

 

Hello thanks for the help. I think the rubber hose is a good guess. I'll replace it this weekend. I know I have a booster not sure of the technical name , think my truck has a hydro boost. I had the diaphragm replaced last year and it works good. Might their be a check valve sticking? I'll see if the hose fixes it.

 

does ant one know the napa or advanced auto p/n for the rear hose?
