Maiden Voyage with Trailer Brake issues!
 
1 Attachment(s)
I have been working on the GHOST (66Burb) for about one year getting ready for camping season this year. Thought I had everything in order for the first outing. New brakes, wheel cylinders, hoses, new master cylinder and it has factory Power Brake unit. Shasta trailer weighs 2820 loaded and has a 360 # tongue weight. Single axle trailer has electric brakes which I went through and they work fine. New electronic brake controller. I can manually lock up the trailer brakes. I came down a 9 percent grade which was about 1 1 /2 miles and was assisting manually with trailer brakes. I was completely out of suburban brakes when I hit the bottom. They cooled off later and worked fine on the trip home. (avoided the hill) Pretty scary!! Any ideas? Or time to gear up and add power disc brakes? I was hoping to keep the burb somewhat stock. Will disc brakes work with the stock 15 x 5.5 inch wheels I am planning to put back on?

Use the engine to slow yourself down, another words downshift and do not ride the brakes but gently apply them periodically. Pay attention to what the truckers do.
Years ago your drum brakes did the trick, they will work now.

I have the same rims on my 65, but 5 lug from an 86 Suburban, and have disc brakes. I put my discs on back in the late 1990's, from Master Power Brakes. No issues. My rims are 15X8, on the ground, and a matching 15X7 for the spare. Hope this helps

Scary. I have the very same concerns. 3400 Lb vintage boat/trailer combo without trailer brakes and stock drums makes me worry. Add a camper on the back of the truck and it's curtains for the family. Really not sure how our dad's did it back in the day. Plain ignorance or bigger b---s, I guess.
No, your stock wheels from 65 won't fit discs. You gotta go with a slightly later wheel.

The problem that nearly every "normal" (non professional) driver makes is going downhill too fast to start with. Many feel that they have to do the speed limit downhill and that is what gets most in trouble. On a 9% grade with a relatively heavy load (trailer is ~1/2 that of your truck) you should likely start the hill at half the speed limit. Of course it all depends on weight, length of hill, manual or auto transmission, etc. But I've found that on grades >6% a typical SUV / small truck should cut the speed limit by at least 1/3. Dont worry about holding people up behind you, they can wait or you can pull over at a pull out and let them by later. Its better to slow them down than to not make it down safely. Even if you have disc's instead of drum breaks, makes very little difference. While discs will help stop you better, they can overheat and catch fire just like drums.

I wish I could have said it like this. 100% true

Thanks for all the input. Gearing down will be a little tough with a 2 speed PowerGlide, but approaching the downgrade a little slower will sure help. j

I agree that staring the decent at a lower speed will definitely help. With brakes on the trailer, I don't see that there should be a problem. Maybe the trailer brakes are not engaging with the Burb brakes as they should.

I have towed with my Burb but not with that much weight and a 9% grade at the same time. Although I have towed a trailer probably 1/2 that weight and no trailer brakes, to Yellowstone and all over there for a week with no issues. My Burb has power drum brakes, but a 454 and TH400.

I have never pulled a single axle trailer with brakes but MANY dual axle trailers and the trailer brakes on them if new will stop the truck.

Back then nobody had good brakes so you were less likely to rear-end the car in front of you.

Even with no load I sometimes get a bit of a scare when someone in front of me has a lot better brakes than I do. :ack: :eek:
