SRAM makes good.

The SRAM Guide line of brakes really are the next level, and the Ultimate is SRAM’s latest top-of-the-line offering. The Ultimate pairs carbon fiber levers and titanium hardware with its all-new S4 4-piston Caliper. This combination means pro-level XC-race weight with motorcycle stopping power.

Whereas the more basic Guide R brake relies on the proven DirectLink lever design, the RS, RSC, and Ultimate models step it up with SwingLink. SwingLink utilizes a specially shaped cam that not only requires less travel and force to produce proportional amounts of pressure, it minimizes the "deadspot" of lever travel. Paired with the new cup-seal timing port closure system, this means that you receive perfect modulation immediately. Once the lever is squeezed, a cup seal swiftly passes this area and closes the port, pressurizing the system and forcing the pads to the rotor. The Ultimate's contact point adjustment feature is found just behind the lever attachment to the master cylinder, making it quick and convenient to dial in the brake's feel.

The caliper paired with the Guide Ultimate is the powerful new 4-piston S4 model, and it comes with SRAM's steel-backed Trail pads for incredible stopping power. The forged aluminum construction means long-term durability and ease of pad removal via the top-loading design.

Another feature exclusive to the Guide Ultimate brake is SRAM’s Bleeding Edge technology, which makes your brake bleeds easier and more effective. In the past, SRAM’s brakes have been notoriously difficult to bleed properly. Bleeding Edge does away with these bleed woes with new bleed porting and a new fluid path that make it easier to push fluid through the caliper. The dedicated bleed adapter for the S4 caliper plugs into the bleed port and seals the system to minimize air contamination and fluid loss.

The SRAM Guide Ultimate Disc Brake comes as a Front/left or Rear/right lever and caliper configuration, with the package-completing Centerline Rotor sold separately. The lever assembly is also Matchmaker X-compatible, meaning you're able to run your various controls off one tidy lever clamp.

  • Familiarity: I've put it through the wringer

The brakes were a bit difficult getting set up just right so there was no rubbing and no noise. However, once they are set up they are perfect going forward. They make no noise and ride smoothly.
With these brakes the weight is low and the stopping power is efficient.

Heavy Rider Must Have

  • Familiarity: I've put it through the wringer

These powerful brakes are a must have for heavy aggressive riders. I am 250 lbs but these brakes stop me on a dime, every time!! I have a set in my AM and XC bikes.

Don't loose the rubber bleed port plug

  • Familiarity: I've put it through the wringer

Their well thought out bleeding edge port has a fatal flaw: the plug doesn't stay put and isn't available without a bunch of parts you don't need.

I have these brakes in 2 different bikes that are ridden 3-4 times a week all year. Never once has the rubber stopper fallen out. Likely user error.

Killer brake killer on the bank account

    I bought because I wanted more stopping power. Its bragging rights for sure. Tons of adjustment for riding . Carbon levers and Titanium bolts and the set of matchmakers for your shifters round it out. The only difference is the cylinder/lever on the other guide line of brake. I had envy after I bought and used . But hey you can't take the money with you when its time to check out. Basically they are really nice /quiet wet or dry and have extreme adjustability. Pair with nice vented rotors and your golden. For the money if I could do it again id most likely buy the RSC set ... I'd gotten a call from back country the next day saying thanks for my order. The guy even mailed me a note saying thanks and tosses in more goat stickers... Way to earn more of my business....

    The perfect recipe

    • Familiarity: I've put it through the wringer

    These brakes are great. The four pistons in these brakes are perfect for heavy enduro riding or xc racing. I like the extra stopping power over the 2-piston Levels. These brakes keep the weight down and have a great feel!

    Are the brake levers adjustable? Thanks

    Hey, the brake levers are easily adjustable for reach and contact points. Please reach out to me if you are interested and I can help get you setup with the right brakes for you.

    Brake levers wont return to normal posit

      I moved away from Shimano hoping SRAM had done homework right finally on their brakes. Guess not! its been 9 months since I had the Ultimates and although they feel powerful and have amazing modulation, I am noticing that the brake lavers are not returning to original position due to that loose power and zero modulation causing loss of braking control. This issue seemed a lot worst on hotter days. Today I found out there are many people out there with identical issues ( at jenson usa check reviews under Item #: BR197C00 ) .

      I've experienced the same thing and need to replace the outer cup seals. Sigh...

      I had the same issue with BOTH front and rear brakes after sitting (indoors) for a month. Less than a year old and were totally fine last ride. Local bike shop said it's common with all the Guides and they have to take apart and grind some part so it doesn't bind up. They said it's cheaper than buying new brakes and new brakes will eventually do the same again anyway so better to just fix it. They are trying to make a warranty claim with SRAM and if not they say they will only charge me $20 each (price they quoted to bleed brakes when they assumed that was the problem). Awesome shop. Otherwise yes fantastic brakes.

      The new internals cost around $30.00
      Local bike shop wants $25 to replace part or $40 with a re bleed. Super expensive. I hope these new internals don't wear out in 6 months.

      The Ultimate Brake

      • Familiarity: I've put it through the wringer

      The Sram Guides have amazing stopping power, adjustment and control. They are super easy to trim to fit the bike, bleed, change pads and the Ultimate's come with the benefit of a carbon lever.
      The matchmaker keeps everything simple and clean on my handlebars too. I have a mix of the Ultimates and RSC Guides on my trail and DH bikes.

      does the set come with front and rear callipers and levers?

      Hey Jimmy,

      The brakes are priced individually for the front and rear lever/caliper that come prebled. Don't hesitate reaching out if there's any other questions I can help out with!

      Best Brake on the Market

      • Familiarity: I've put it through the wringer

      The S4 caliper is simply outstanding. On your first ride you will be braking too early and too much. The lever feel is very firm but still modulates better than anything else. Whatever you are riding now, this is a noticeable upgrade.

      Compared to m8000s? I can't complain about the new XTs but always lookin for better too!
