I'm looking for alternatives to my crappy push/pull wheelchair breaks and just stumbled on ADI's disc break system (http://accessibledesigns.com/para.html). Has anyone tried this? Looks pretty sweet.

why do you want breaks on an every day chair??

Most of the time you don't use them and they become something to go wrong!

As an incomplete walker I rely on my brakes for when i plunk down heavily in the chair after losing my balance. if brakes are not engaged chair slides dangerously away from me. they are also useful on uneven floors.

I had some coversations with ADI about there disc brakes a few years ago as i can get access to a press to press the insert into the wheel I just wanted everything sending over for me to fit them but they also told me that having the brakes will add a minimum of 1/2" width to either side of the chair because of the disc and caliper but having thought about it I just could not justify the expense of having them so i just stick to my scissor wheel locks and as I only really use them for transfering it seemed a bit over the top just to have a disc brake system,I know that you can use them for actually braking like you would with a push bike but to be realistic how often would you need to do this in my opinion and thats all it is i can't speak for all they seem to be just a bling factor to look good and they do look very good thats what interested me to start with but and i suppose if I did have money to throw around i might have bought them but for how much i would use them they aint worth it for me.

I like the idea of the positive lock, the pin mechanism that you can get with the D Lock system, no extra width either.

Couple of questions from a newbie if you don't mind.

I would like to remove the brakes because changing wheels is a pain with them, but how do you keep the chair from rolling without them?

&

What is the advantage of the positive locking pin over standard lever-on-tyre brake if all both do is stop the wheel from turning?

[Apparelyzed]

I wonder how the discs will fare when the wheels are off, as they may be in contact with the ground, causing chips and potentially warping the discs.

I saw on the homepage that the chair with no wheels on has tipper bars on it, so in that case the discs would be protected. But most people I know don't use tippers, as they are too restrictive.

The D Locks, the pin is engaged with the move of one small lever, easier to reach than scissors ets and also do not interfere with transfers.
Also there is no risk of the brakes slipping if the wheels are wet or you are on a significant gradient.
Having said that I did look but I don't have them.

That's a great point, I didn't even think about that.

The disc would hit the ground when the wheels where off so I can't see them holding up to the abuse they would get on an every day chair thats why i think they are more a bling factor than useful asset,this is what put me off going ahead with getting them the cost far out ways the actual practicality of them I would rather save the money towards a new chair when I need a new one.
