Greetings all, I moved my '76 yesterday after a bearing re-pack and rebuilding the brakes. Haven't had it on the road yet, but noticed that the brakes were squeaking at the slightest touch of the brake pedal. This is not my first brake rebuild, but I'm curious if anybody else has experienced this? Maybe because everything still needs to settle in?
How much have you driven after the brake job? Iron brakes (most vehicles/trailers, drum and disc) can flash rust after sitting for a short time, especially with high humidity. This can cause the first few braking events to have noise or vibration. But if you've had a few good stops and it's still squeaking, that's probably not it.
Squeaking can also be caused by new shoes on old drums, if the drums haven't been resurfaced. Once the friction surfaces wear down to match the grooves of the drum, it should improve.
I'm no expert, this is just from my experience working on my own cars/trailers.
I had the drums resurfaced last fall, did the bearings and brakes, but never went anywhere with the trailer. Bet you're right, the drums have surface rust on them. I only pulled/pushed the trailer about 100 feet, took it off the lawn and parked it on the driveway, I probably should have taken it up and down the street a few times to break everything in. I did the brakes on our '70 Compact and '72 1400, so the Shasta brake system was no stranger to me, but those trailers never made any noise at all...but now that I think of it, I started towing them soon after I did the work. OK, I feel better now, thanks!
