Shimano SLX BR-M675 Disc Brake

Shimano SLX M675B Pre-Bled Disc Brake

Coming to a stop is much harder than it sounds, especially when you’re bombing down a run at 30 miles an hour. The Shimano M675 brakes provide ample stopping power to bring you to a complete halt.

These hydraulic disc brakes feature Shimano's Ice-Technology. Heat from friction can cause rapid temperature increases and cause brake fade. Ice-Tech allows heat to dissipate quickly to keep braking even and predictable. With the decrease in temperature, brake pad life is also prolonged.

It doesn't stop there. SLX brakes adopt many of the top-end technologies from XTR and XT, including Servo-Wave modulation and ceramic pistons, making these brakes feel amazing and powerful. These brakes require only a single finger to reach full braking power. At a lower cost than XT and XTR, these benefits are hard to beat.

Finally, SLX brakes are easy to gravity-bleed, meaning you get back on the dirt faster. One-way bleeding is much faster and cleaner than competing brake bleeding systems.

Great brakes at a great price
This is an awesome set of brakes. Coming front a basic set of Hayes hydraulics this SLX set is leaps and bounds better. The stopping power is awesome, the lever feel is also good.

As far as installation goes, you will probably need to trim the brakes hose. No big deal. The simplest way to do this is to take the pads out, and give the lever a couple of squeezes so that the pistons poke out a little. Then take off hose at the lever, trim it where you want to, and put in the supplied barb and olive. Then once you attached the house, open up the big fill port on top of lever and spread the pistons apart using a tire lever, some fluid will ooze out. Bam, done. Now you are ready to ride your awesome set of quiet and powerful Shimano brakes.

Great stopping power at a good price
These brakes came stock on my XC bike and I thought I would have to replace them for better power and modulation, however, after a ride using them I knew that was not the case. I like to ride very technical trails and race XC and these brakes have proven to be all I need. They are not the lightest out there but they do their job well

As always, Jenson does a great job of delivering solid products in a timely manner. My order was currently out of stock, with a projected arrival date to the warehouse, and then an additional projected date to be delivered to me at home. All those dates were 100% accurate. Once again proving the reliability of Jenson USA!

Sweet stopping mechanism
I bought these for my mountain bike as an upgrade. I liked them so much that I bought a second set for my commuter bike. I can skid my tires by pulling with a single finger.

Install was a snap
I'm the guy that fixes everyone else's bikes and had noticed over the years how much I liked working on Shimano hydraulic brakes compared to anything put out by SRAM. I was able to cut the cable without bleeding them and you can store your bike in any position you like. Brakes work perfectly out of the box with minimal break-in and the stopping power and modulation are a big step up from the BB7's and Juicy's that I've had. Lastly the price cannot be beat.

PROS: Easy To Install, Amazing value

CONS: Didn't buy sooner

These brakes are pre-bled, but they have full-length lines which means you may need to cut and bleed them to get them to the correct length for your frame. As such, Shimano does include the compression olive, needle, bleed block and hose clamp block.
are they pre bleeded?

BEST ANSWER: Hey big_bru, yes these are in fact pre-bled! I've gone ahead and updated the description. Thank you!
