Going from drum to disc brakes. Any suggestions are greatly appreciated

are there such a kits ? never heard or seen it

 

I do not know about 1991 but the ones from the early 80's had different bolt patterns on the axle for the backing plates.
Buy a cut off with disc brakes if you want to go that way.

Why… the drums worked for the last 1.6 million?
Sorry maybe my opinion is tainted with the 100% increase in maintenance when the buses switched from drums to discs. They were both hydraulic brakes so maybe that’s the problem. I know there’s supposed to be some advantages.
I wanted to say I heard at some point that the conversion was 3-4k but I don’t know what exactly was involved or what rears.
I wouldn’t think that a cutoff with the idea of cutting the frame would be worth it. I also hate the idea of cutting a perfectly good frame and welding it back together and I have been in the welding business for a long time.

 

I can understand that..have you priced the rails new makes me feel better about the cutoff idea. Maybe get one that’s really long and splice near the cab…that usually clears up the old age frame problems

 

I would think that’s with the holes drilled because I priced some about two years ago for a 250ish wheel base truck for around 6 k but that was just heavy spec blank rails

 

Its gonna cost you 10 to 12k just to get the cut off glued on plus the cost of a cut off so your gonna have ruffly 16 or 18k then the cost of the motor swap in a 1991 with 1.6 milliin miles ...you must really love this truck
