Brake Lever Internals Service Kit, Rebuild Part Piston Assembly for Sram Guide Level Code DB5,Never Expand, Never Stuck or Oil Leakage

Worked really well. Sat the bike in the hot sun on a 90 deg day and brakes still felt perfect, no sticking.

They fit it perfect and solved the sticking problem. I also ordered the bleed kit.

Worked great for my Level TLM, the pistonis a whole mm small in diameter - I now have brakes that aren't half stuck. Words of advice:1. Good circlip pliers are a must! You need long nose ones that have really small tips. The junk from Harborfreight was not the right tool for this job.2. You don't need to disconnect the line. I was able to do the swap while holding the assembly in my hand in such fashion that the piston that gets replaced is perpendicular to the ground with an open end facing you.3. I did it as described in # 2 and i DID NOT have to bleed brakes ($ saved!)Updated parts from SRAM is still made out of plastic - what a shame.

Wrong description!This is the short length piston.If you have GUIDE RS it won’t work.1 3/8” long.RS needs 1 1/2”.Otherwise looks good!

The description doesn’t say it’s compatible with G2’s, but they fit perfect. The spring it came with was too long, so hang onto the original spring. Otherwise, it felt good to not trash a year old level assembly and save a couple $$.

This part is well made and solved my sticky lever problem. Other reviews say that the spring is too long but it worked fine for my Guide R lever. I bet this will not swell like the original plastic piston. Very happy with this part.

I put these into my Guide RS brake levers from 2015 and my brakes work so much better now. I was having problems with them staying engaged after I released the lever. It was especially bad on hot days. I thought this meant moisture in my brake lines so I flushed them more than once with no success. After putting these in and bleeding my lines my brakes are great.The original plastic parts swell and jam in the cylinder. I’ve had my bike out on 20+ rides since installing these and have had no problems with my brakes!They aren’t easy to install but they are doable if you’re handy. You need this tool or something similar https://www.amazon.com/gp/aw/d/B07WMMKFNG?psc=1&ref=ppx_pop_mob_b_asin_title to get the snap ring out. You also need #9 torx bit which isn’t common but I was lucky enough to have one laying around. YouTube has plenty of people taking these levers apart so I recommend if you have sticky old guide brakes, you should do this immediately.

Works as intended, I purchased because one of my factory piston was swollen. Now with this new piston I will never have that problem again. Installation was super easy and seems like the spring that comes with this piston is much more stronger than the factory one so now the lever returns much quicker!Very satisfied with the product performance.
