as above, any good?

I've got them fitted to the rear of my Sylva Mojo, seem to work just fine. I had the option of them or sierra non vented but went with these so I could buy em new and go for age related plate.

If you decide on hydra mech calipers, I have a pair with discs, brackets and handbrake cables.
U2U me if interested.

The only problems I've found with them is they foul any upright or axle that uses 5" tube in the design, such as the Haynes Roadster, the boss for the hose inlet prevents them from sitting square so the tube would require modification to allow the hose to be fitted.

Kind regards

John
