Wheel Removal with Magura HS33

[PerpetualMotion]

Hi folks,

My Kalkhoff Pro-Connect is fitted with magura HS33 hydraulic rim brakes. All functioning well, but I need to take off the wheels to switch the tyres to studded winter tyres.

With my old bikes and regular mechanical brakes I am used to unclipping the wire to open out the blocks and remove the wheel without having to deflate. How to do this with the HS33 mechanism? I cannot find any documentation outlining simple basic maintenance with these brakes.

There is a small metal lever which says "close" and "open" by the brake block housing. That seems to release the block on that side. I am afraid to do too much without guidance otherwise I am liable to end up with a pile of screws, lugs, springs, things, pivots, rivots and probably brake fluid all over the floor...

Thanks for any help!

Do you already have the HS33 manual from the Magura website ?

You do use the lever when you remove the wheel. I don't think you can do too much harm - you might have to realign the blocks a bit on re-assembly but it is not like a full install (and that is a right pain).
