i think i used a 79 thunderbird master cylinder a few times.  Pretty sure they were non vacuum boosted and definitely 4 wheel disk.  The bore is pretty small so pedal effort is easy.  Very easy when put over a vac booster.

I have a 240A and was constantly having problems with the brakes on it. I removed the rear brake system from the transfer case and had piece made at the machine shop to bolt a Chevy pickup rotor to that went between the transfer case and the yoke to the rear end then I welded up some brackets to mount the calipers on and used two calipers and a line lock for a parking brake and now it's got the best brakes of about any skidder that I have ever been on . No matter if the motor is running or not the brakes work great.

If my forklift stalls its got no steer or brakes.  But it rolls real good!

Id never dream of building a machine with brakes that quit with the engine.

Mike,
What span of years would the Ford Exlporer with the 8.8 rear be that would have the type of caliber you described? Thanks for all the great info.

Sorry, I got my truck parts mixed up.  I dont think 8.8s used a cable to the caliper, i think it was a shoe in hat type park drum on those.  Its been a while.  

Maybe it was S10 or monte that had it, but for sure 88-90 eldorado.  Here is a cheap refurb.  Theyre normally like $100-200 each. Spray a bunch of WD40 into the hydraulic line port and cap it so the piston doesnt sieze in the bore from condensate and rust. 

1988-1990 Cadillac Eldorado Brake Caliper - Brake - AC Delco, Rear 88-90 Eldorado Brake Caliper - 2835-01233431 - PartsGeek

AA-mfg.com should stock cheap weld on mounts for that caliper.. Like $10 or so. Itll use slide bolts IIRC.

Thanks again Mike.  I looked up that caliper.  I never ran into one that had the e-brake cable.  Thanks for breaking the trail on this and saving us all a bunch of time!

I'm currently converting my 201B to a disc brake system.I am using a rotor and caliper off of a dodge dakota 4x4.I was taking pics as I go so I can put it on here when I'm finished but I had to stop my progress because I had to rebuild a 353 and just as that one went out the door another buddie lost his skidder engine so now it's another 353 to do.Is your transfer case a Rockwell or a New Process?
Hey do ya got you picture to upload like to do my 200 over like you are doing and a few pics would be a great help

I have a 240A and I did a caliper and rotor conversion on it. Remember if you already have a master cylinder and brake lines half of the setup is already there. I used rotor and calipers for a Chevy S10 and brackets made for race cars. But since you have to do some welding work and machine work anyhow you can use almost any calipers and rotor. Just remember to add a line lock or you won't be able to set a brake while you get off the skidder .

Glad to see this post resurrected, I am tuning up the old 230 and working towards this brake conversion any pictures appreciated. Spotted the Dual caliper 1 rotor more stoping power. Thought I would put rotor on front shaft and one on rear, in case of driveshaft failure. Also ebrake cable was mentioned earlier as an alternative to line lock.

finally got the conversion done on my 230. used rotor and caliper for 1995 volkswagon jetta. and machined a spacer to move disc out for caliper clearance. turned out well. also installed new master cylinder and leverlock brake lock valve  >
