Thinking of putting air bags on my 83, S3.

Has anyone put air brakes on too.
Been looking but can't find anything.

Anyone tried this before?

 

[kermit_rr]

Why would you want to? Is it going to be used on the road?

There was at one time an air brake set that was available. This was for the Land Rover to tow air brake equipped trailers.
A mate had an early Ninety with it fitted. We think it was for the ability to move empty trailer's around a site/dock. The landy's brakes were just the usual ones.

Why are you fitting airbags? If it is to replace the leaf springs with and airbag suspension then I bow out have have nothing to add.
If it is to act as "helper" suspensions to increase the carrying capacity then that is not how suspension works and you probably need a new set of springs rather than airbags. Weight rating is determined by the axle rating. Adding airbags wont increase the carrying capacity or improve the ride vs new correctly rated leaf springs.

Why do you want airbrakes, what is the intended use, what befit over standard do you hope/think they will bring?

I would be amazed if you cpuld get any air brake components small enough to fit.

And have any HP left to move the vehicle....

I would expect these days for something as small as a land rover you could use an air tank and an electric compressor. You can get some very good electric hydraulic setups now, don't see why this wouldn't be the same. the real question still remains why!

That was pretty much the system that was used 40 years ago. However nearly all air brake systems today use compression rather than the vacuum of old.

I was referring to compression, you can get some very powerful electric air compressors these days with developments in motor technology.

 

[lynall]

Air brakes use large amounts of air, most large truck compressors are 750cc capacity and they take some power to drive them.

Yes I get that,. The question remains why would the OP want to unless it is for a job like mentioned in my post above?

 

[kermit_rr]

I don't see what value air brakes would add.

Nor I. But so what? If we were sensible we'd drive Toyotas.

How would you get an mot? Insurance would be fun. It would weigh a lot more so not so much wiggle room for payload/towing

 

[Wildefalcon]

Good practical points. But series ownership is very personal, so if OP wants air brakes, and can do the work/admin, so what?

Bit pants if you can't drive it because no MOT or insurance

 

[Wildefalcon]

True for anything. But no reason to assume that the vehicle couldn't be fully legal after the modifications.

 

[lynall]

I think the original question is plain daft, air brake even on old ****etrs are more complicated than hydraulic brakes.
No insurance company on the planet would touch it with a barge pole.
