How far can you stretch a ski brake?

post #1 of 20
Thread Starter 

I have a ski that needs a binding.  It's a 106mm underfoot.  Bindings I'm considering are Look Pivot 12/Rossi FKS 120.  They come with a 95mm brake or a 115mm brake.  However the store has no 115mm model.  

 

Can you stretch a 95mm brake to accommodate the 106mm underfoot?  Any potential problems?

 

Will the 115mm brake be too big?

 

Thanks!

The 95 brake will likely fit a 100 waist, so very little bending will be needed.  However, brakes are a PITA to bend.  I would just buy some Marker Griffins with the 110 brake.

Fwiw the FKS 95 appears a little narrow... I've got a pair now & there's no way it'll fit 100 w/o getting ugly....

Go 115

115 - 106 = 9 divide by 2 = 4.5mm wider on each side. About the width of two nickles. I've got Looks with 82 brakes on a 70mm waist, 6mm/side, with no problems. Sounds like it should work. Bending those arms are a bit of a bear (never add heat!!) but with a solid vice, good vice-grips and a sturdy pipe it's not hard.

I just bent a pair of skinny race FKS brakes to fit a 110mm ski. Any of the brakes will bend to fit your skis.

Yes ya can can stretch any brake, but will it stop your ski when released off your foot. Just send it back to look and rossignol and they can press in the proper brake ya need. Yes one can bend one about a cm. but why? Just send back and get a new one presses back in at the proper size.the pivot binding brakes are pressed in and cannot be changed out in any shop while being approved by the manufacture. Bending is not the best choice for this application I feel. Just thought ya should know.

With the right, simple tool, they're easy to bend. An old length of pipe roughly the diameter of a ski pole does the trick. It's all about the leverage. The non-race FKS and axial series brakes generally will easily work with a ski width up to +1cm.

Thanks for the replies.  There seems to be no general consensus.  Yeh I had seen that link in my web travels but I didn't want to spend any more money on the binding.  Also going with Marker Griffons changes the whole philosophical choice of bindings.  I guess I was thinking turntable design since skiing with a longer fatter powder ski increases the risk of wipeout on groomed terrain…   I think the consensus leans to go with the 115mm brake on the FKS 120.  Anyone have complaints about 4.5mm of space on each side?

I will go to 100mm with the 95 and over 105mm, I will go with the 115mm. The Pivot brakes to not take to bending as well as some others.

I've seen skinny Salomon 997 brakes bent to fit a Spatula.

 

 

That said, brakes don't work so well on pow skis in steep, untracked snow.  I've watched a ski rocket down the mountain on more than one occasion.

This is a good topic for a whole different thread..How come brakes on wider skis don't have super long prongs or some kind of umbrella device on the end of the prongs that deploys to grab better in powder?

I've got 115 Fks on a 120 - it was just the black plastic binding a bit on the edges - dremeling solved it.

Keep in mind the brake arms tuck in a bit when fully pushed down by your boot.  So a wider brake typically is not sticking out when skiing.

I wonder if the binding warranty is voided by stretching the brakes?

For one, no you can't send FKS into Rossi and get new brakes pressed in. Rossi/look only sells the the heel as a unit, and charges 130ish for it. That's more than I paid for my FKS new. Yes, shops can change the heel peices, but most people won't fork over 130 just for new brakes.
Second, people have been bending FKS race brakes for years before there was wide FKS brakes, and they work fine. I have over 200 days of skiing on mine without a single run away ski.

Both of those started out as skinny ski brakes, and have plenty of reach.

As for the OP, why not see if the shop will order 115mm heel price and swap it out?

Last time I checked, FKS/Pivot w/115 seemed obtainable at decent prices online.  I try to stock pile these, so I look around once in a while.

I thought about doing that, but after talking to some people with more experience, decided to just buy the right size.  If they snap, it's expensive to replace the brakes at any width.
