The e-brake will hold when parked uphill fairly well but parking on a downhill the e-brake hardly holds at all. Is there an upgrage or something else I should be looking at. I want to add a tow hitch and use the truck to launch my boat so I need a good e-brake. | | | | | Joined: Mar 2005 Posts: 311 Shop Shark | | Shop Shark Joined: Mar 2005 Posts: 311 | I cannot specifically help you as the E-brake "should" hold the truck the same uphill or downhill. But if you do not have the service manual to your truck here is a link: http://chevy.tocmp.com/1948_51truckshop/index.htm Somebody on this site will have better trouble-shooting skills and lead you in the right direction.
Always get a 2nd opinion, especially if I am the source of the 1st opinion.

Without seeing what they look like, the only things I could suggest is make sure the parking brake lever inside the drums is free and applying pressure equally to both shoes. Also, add a dab of white grease (lithium greas) to each of the spots where the brake shoes come in contact with the backing plate. Take care not to get any on the friction linings, of course!
You said the cables are new? It might take some time to stretch them a bit before they will apply good, even pressure. Try tightening it just a bit to see if that helps. And check to see that both rear cables are getting even pressure from the intermediate cable. To do that, set the brake and tug on both cables individually. They should have the same give.
If a 'truck' is only used to haul butts to the mall, then it's not a truck - it's a car with a roadster trunk.
Old, rusty and ugly - might be me or my fleet. You decide!
