I ended up here in 2023, with a SRAM RS Guide that was not part of the 'affected' series having the stuck lever piston. 2 high points measured 9.55 and 9.50 vs 9.40. Took them down to 9.42. I was less patient and used 340 grit for the first reduction, then 1000 grit to finish, finally using wet 1000 grit emery paper to polish. Love the use of the drill as a mini lathe. Very good idea.
Thank you for such an informative video. If I replace the O-rings with new ones, is it still necessary to sand the piston to 9.4mm in the three places described? I purchased a repair kit, but it does not have pistons, just the O-rings..
Plastic pistons (will lose shape) of different sizes (why?) for the same brakes: makes no sense. Exept selling the 30$ rebuild kit every year. SRAM can not be trusted.
I'm disappointed with Sram. I upgraded from Shimano to Sram Code R and they were incredible good modulation and stopping power but the build quality is poor and can be dengarous. I can't understand the logic behind the design, brakes are the most important thing on the bike and looks like safety is not a priority for Sram. The piston in the lever is made of plastic (in Shimano is metal) and will deteriorate quite fast and it will get stuck, the rubber seals are not godd quality either. The pistons in the calipers get stuck as well and resulting in unbalanced braking(3/2 working out of 4).All of this happened with me a little over 1 year wit only a few rides, noting extreme. It's insane making this compromises just to shave off a few grams. This brakes are unsafe and they should not be allowed on the market.
I agree with most of you。 SRAM/ROCKSHOX likes to set useless technical threshold in product design. I think it may be used to prevent customers from repairing themselves. We all think it is unnecessary for many designs, but they insist on doing so (perhaps because of the design patent). The brake of SRAM should be maintained every six months, which can greatly reduce the occurrence of faults.
@@ezmtb by maintenance you mean buying the repair kit and changing the parts? That will be almost 100$ every 6 months. The issue is with the seals/inner components, the dot fluid deteriorate them Shram not using automotive grade components. Shimano don't have this issue as they use mineral fluid the lever piston is aluminiu (shram plastic) and the caliper pistons are porcelain(shrams are plastic and gets deformed by heet) clearly the choice of materials are superior on Shimano brakes by adding a few grams comparing to Shram. So when you compare them keep in mind plastic vs aluminum and plastic vs porcelain.
@@albertszabo5289 Dot brake fluid is easy to deteriorate and more corrosive than mineral oil. Changing the high specification brake fluid every six months will help a lot.
@@albertszabo5289 Yes, that's why I say that SRAM often deliberately makes unnecessary designs to improve the user's threshold. For example, the bleeding edge interface, in principle, is the same as that used by Shimano, but its design is very complex, and its operation is very difficult, and there are many details to pay attention to bleeding the caliper, maybe this way can improve there sales of the tool. lol...just for joke... Maybe designers have their own ideas, but no matter what, for users, the experience is not good enough.

I like that you use the Shimano funnel . Easier than playing with 2 syringes. 👍
谢谢你的视频，我安装了一个新的 lever blade 在我的code rsc上，可是这个lever 根本无法下压，不知道是不是跟视频里你介绍的一个问题，另外我打开那个油压室，里面都是黑油，但是并没有发现钢珠还有弹簧，我是不是直接该直接换个刹车😅
Can this bleeding procedure be used on shimano, this looks very convenient
Thank you so very much, I just fixed my front Break level. They way you explained it was prefect.
This video is the best for solve the problem! Thanks

Yes, it is necessary
Thank you. I have search and your video is the best one to do the repair.
That the reason because i still use a 2012 sram code brakes. Better ever!! ALLES GUT👍🇩🇪
Thank you for your effort sir. Outstanding tutorial!
Yeah let me follow along to this
awesome tutorial mate
Thank you very much, a wonderful instruction video.
Superb mate. Thanks
Its not fair you chaince you guys good in everything ;)
Lets try this even i ordered new code rsc to replace the broken guide
Does this apply to the code r aswell?
Such a great video. Thanks.
you have a different approach in bleeding your brakes, it's just like with shimano.
Alan common sense is a beautiful thing. This guy DGAF. Using 2 syringes is a mess
Superb sir!
Thanks man! It helps a lot.
5:40 what is that name
NEVER EVER work with sandpaper near sensitive parts !
Rinse well and dry the piston before assembling.

@@ezmtb ok but why Shram is not using automotive standard components? You don't change the brake fluid in your car every 6 months.

china
Sram is a shit .
Any Shimano alívio is better than a top Sram brakes .
