I know they have warranty, but I'm not going to send them back for something that I can fix in 20 minutes at home.

A friend of mine had this brakes on a trials bike and had a similar experience to mine.

You can use them with nearly every mineral brake fluid. They're known to work even with olive oil or water (not that I recommend it!). The fluid isn't going to heat up, so no problems with boiling. Though if you dare to use water (some trials riders did, since it seems it improved the feeling) , it may freeze on winter.

Was thinking on mentioning water, as have heard the same for trials bikes, but you really need to know the limitations with that, and being a closed system, if you let it freeze, suspect it will damage the brakes, probably beyond repair.

Kool Stop does,for sure. There are companies specializing in trials bikes that make pads with different compounds..pads that give full lock up,pads that modulate,pads for ground rims or unground,etc.

The brakes that Magura makes for TT bikes are nothing like the ones we are discussing here. The HS series brakes have a specially designed pad that snaps Onto the piston with no added hardware.

When you bleed them with water you have to take care not to use them in freezing temps, obviously. Moreover, they're more prone to leaks when filled with water. I suppose that happens because water is less viscous than oil and also may affect the seals.

Anyway, even oil filled, mine have leaked a couple of times on the lever without apparent reason. After cleaning the piston and cilinder on the lever they were back to normal (non leaking).

IMHO, they require more maintenance than a hydro disc (even if it's an Avid or a SRAM), but if you can't fit a disc, they're probably the best brakes available if weight is not a concern.

re using water, as an emergency I sort of understand, but as someone mentioned, you really dont want to use water as freezing issues will damage seals etc.
I once had a motorcycle used racing, and requirements were that anti-freeze/water mix was not allowed on track, as a leak would be very slippery and wouldnt evaporate, so those of us with water cooled bikes removed it and replaced with water.
Forget it and store the bike in an unheated garage, and voila, damaged head gasket. I was lucky and got away with only that , no cracked parts.

I wasn't talking about Magura TT brakes.. The HS series brakes have been around for years and are still one of the go to brakes for trials. Companies have been making pads for them for as long. I have a set of HS33's on my Curtlo,running Kool Stop dual compound pads. I used to use these also: https://www.webcyclery.com/product/j...-pads-7819.htm

Ah, I equated trials with time trials, entirely different bikes and brakes. I have serviced the RT series on TT bikes, and they will take a regular garden variety pad.
The pads in your link do look like they fit the HS series. Good to know, thanks.

Bumping an old thread.

I have a couple of questions (for the HS11 rim brakes, FWIW):

1. Is this Torx 25 screw used just to adjust the reach (short/long fingers) intially once and for all, or must it be tightened as the pads wear?

2. When replacing old pads, is an extra step needed not mentioned in the official video*? What to do when the new pads touch the rims, and won't let the wheel spin?

Thank you.

Does Magura make brake levers for their rim brakes that work with drop bars? Not STI type levers. Just simple brake levers.

They did make bar end levers for TT bars to work with the RT series brakes but that line has been discontinued. I donít recall Magura drop bar levers.

if you have a magura bike you want to convert to drops, there is this sort of drop bar option:

Magura made the ultra rare HS-66 & 77 levers for drop bars years ago..You might get lucky and find a pair on EBAY Europe...

I would try using a set of TRP Hylex levers and do a little conversion. Not sure how well it would work but it is an option. People have done the "Shigura" conversions before. However make sure you have a stout rim to handle those rim crushers. I personally would rather run Paul Motolites nothing against Magura I have their brakes on two bikes and love them I just don't need that much stopping on a rim brake bike and if I did I would go disc brakes.
