Yes, all brakes retract into the ski when the boot clicks in, just some better than others. A problem with Protectors is the brakes have to stay below the lateral siding mechanism and are thus lower than brakes on racing bindings.
When brakes are to wide they drag in the snow. But has anyone ever broken a brake due to snow/ice drag? Has anyone ever "booted" out because of the brake? Not me. Skiers obsess over brake widths probably more than needed.
Thanks for the reply.
"The brakes are too wide so they will drag in the snow". That's what I heard when I first ask some stores about this Protectors PR 13 with 85mm brakes on my 66mm skis. However, now I guess if the brake could retract hard, it will be much less narrower than the original width (85mm) so it won't drag while skiing hence no problem at all? I got your point of the Protectors brakes have to stay low due to the design. But I think perhaps the brake width after retraction (boots in) matters more than the hight of the brake position, when we are talking about if they would drag in the snow?
Besides, there are some combinations of 66/68mm skis with 85mm brake bindings sold as a set. Like the Head Worldcup Rebels e-SL 68mm waist with Freeflex binding of 85mm brake, and Supershape e-Original 66mm waist with PPD 12 GW of 85mm brake. Some are even having the Supershape e-Original 66mm waist with Protector PR 13 of 85mm brake. I mean if they're selling it like this, it should just work fine right?
Meanwhile, are there any downside of wider brake when you're not skiing? I think the two only points are: 1) It kind of looks weird due to the relatively large gap between the edge and the brake. 2) It might be hard to carry the skis also due to the gaps as they might slide around? Perhaps someone could illustrate on this part.
I'm planning to buy the Protectors PR 13 and see how they work. Unfortunately, most stores don't have them in stock and I have to wait 2-3 weeks to order a pair... Hopefully it will work so I don't need to buy new skis
. I'll post some images here after the test.
Thanks again for everyone's help.
