am I a looney or what? air brakes on silverado

I found a 1988 silverado 2500 & I want to put air brakes on it, how hard would that be & about how much money?

94 Chevy silverado Blazer 4X4, 350, 700r4, sound system from hell... still drive the dodge mostly

Go get a sample of an air powered disk brake. It is to big for the space around the rear wheel so figure how to make it fit. The leverages and square inches are close. Don't go riding unless it will lock them on rough concrete

The rest is just like the big ones, treadle valve and air compressor/ tanks. Run the lines so they will last

I can't think of any possibility of fitting s-cam brakes/spring brakes, there is stuff in the way or the cans are at risk.

here is air disc brakes:



I wouldn't need as big of brake cans as on a class 7 or 8 truck as this is only a class 2 truck but this is more of a fun project than anything & I like air brakes a hell of a lot better than juice brakes. in any case the truck is getting a lift & I can lift it higher if I have to to make the cans fit. Hell I may be getting a 79 with a 6.2 diesel and I'll probably do it in that instead IF I get that. or if it's at all possible I might toy around in my shop with some old calipers & stuff and try to convert juice brakes to air if that's possible.

Making a new outer pad retainer so it will fit in an 8 bolt wheel and clear the spring is not radical. The 8 bolt rotor is not as thick so the distance between the mounted pads needs to be less and the full sized caliper may spit the pads out with a thin rotor.

Or as an alternative wilwoood rotors may be laminated to get the thickness.

I've got some spare hydraulic calipers, I'm gonna play with those & see if I can make them work with air, if not, It's back to the drawing board

If I remember right brakes are 2500# class hydralics, 120# air might slow things a bit. Normal stopping ought to be around 750#, you might put a gage on and check.

Using the emergency lever from a rear caliper is a thought.

Is there a reason for this or just to see if you can?

I'd have to tweak a few things. the trick there would be converting the cans to pull instead of push such as S-cam & wedge type brakes.

It is just an experiment but if it works I'm gonna do it to all my trucks if it's within reasonable cost because I've lost my trust for hydraulic brakes.
