Re: Disk Pads Failing??????

I agree with a couple other responses that you may need brakes on the second and possibly the third axles, but that is wholly contingent on the weight on the trailer. Not all states require brakes on all axles. Let's say you have 3500lb axles. If your boat and trailer don't exceed 3500lbs, brakes on one axle is okay. But if you have 6000lbs of boat and trailer then you need brakes on two axles. However, I don't think that's your problem since you only towed a short distance before the new pads wore out. Short of defective calipers/pads/master cylinder out of the box or an improper installation, I think your problem has to be a mismatched master cylinder or bad reverse solenoid.

I am examining any possibilities. I, personally, suspect sicking calipers, since dust boots were almost totally distingrated. But that may have been due to excessive heat. To make sure that no pressure went to calipers during back up, I drilled and installed a 3/8" hole so I could insert a bolt to prohibit pressue on line while backing up, should solinoid fail.

Tie Down went out of there way to assist me. Of course, I had to perform the re-installation. I am going to inspect inside of MC to determine if box containing MC was mislabled. Eastern Marine may have gotten incorrect MC from their suppliers. My invoice specified MC for disk braks.

Dingbat,


I examined internal design of my MC and didn't find any valve. At least I know MC was correct one for disks! However, trying to reassemble and compress last seal is proving to be challange. Any suggestions??????

I am guessing, including trailer, 10,000#s.
Well...that's your problem. You have WAY to much weight for a single axle brake system!

Did you happen to tell TieDown about this?

Had same set up with SR AJ of similar weight but one axle with drums a few years back. No premature wear at all.

Re: Disk Pads Failing??????

I know your heading down the path of checking your master cylinder for the residual valve. When you get that put back together, hand operate the master cylinder and the spin the wheel. If there was a residual valve in there, you would have a tough time spinning the tire.

I am not a huge fan of TieDown. I installed the stainless non vented on my trailer and they wore out fast and one disk warped after 1000 miles. I pulled them and threw them away and installed kodiak. This was with brakes on both axles of a load that is less then 7000#.

Turns out (so far) that Tie Down Electric Solenoid was defective. I pull with 4x4 and grandmaw low in reverse was eating pads and studs because of defective solenoid. Tie Down replaced disks/pads and solenoid. I added a ball valve to make damn sure brak fluid doesn't go to pads while in reverse and possible 2nd defective solenoid.
