M116A2 Maintainence and Repair

[FireFighterHill]

Im trying to get the surge brakes on my M116A2 in working order. When I picked it up from GL the reservoir cap was missing and it was full of water.

So I drained the water cleaned out the reservoir and added brake fluid. I followed the TM for bleeding which says to actuate the break away lever to pump the reservoir, this does nothing.

I decided to dig deeper and completly removed the combination pintle and sure brake assembly and the master cylinder.

Several of the bolts were frozen that the pintle hangs from and would not allow the pintle to compress to actuate the brakes, the shock absorber is blown out, and the Master cylinder is full of rust.

Does anyone know of a source for new or NOS master cylinder assemblies?

Also for anyone who want to know the shock on my trailer was made by Maeco there are two numbers on the shock HO8-4-83K and 1844 2

If anyone knows of a suitable replacement shock please share.

Well Ive looked all over and called a few manufacturers and either they don't make the shock and have nothing suitable or in Monroe's case they only sell the shock through Balcrank and they want 48.50 for the shock.

So if anyone knows of any NOS shocks or a cheap shock with part number 1844-2 please let me know asap.

The MC is available thru a trailer supplier. I just replaced one. Search for M101 master cylinder.

I am on my ipod so search is a little hard but I got one at Croft trailer parts. About $50.

I guess I will just have to wait till I have the funds available. I really dont wanna put the hitch back together till I can do it right. I also want to replace all the rusty nuts and bolts with level 10 hardware. I guess once its all fixed it will make the trailer more attractive to buyers.

Here is the page for the parts to fix the surge brake on the Croft website.

Once you start looking at the price of parts the more expensive trailers with functioning brakes start looking like a better deal. If you have to replace the shock, master cylinder and brake away chain you are looking at about $175 plus shipping.
Still if you only paid $200 for a trailer these are nice trailers for $400 that you can pull with dang near any vehicle.
