SRAM 9.0 hydraulic disc brakes
Arno Tatto
SRAM drivetrains are well used on the North Shore because of their simplicity and reliability. Wade Simmons even chose Grip Shift for his signature model Rocky Mountain RM 7. The company with the funny name is now venturing into the world of disc brakes and nsmb asked me to test a pair. SRAM hydraulic brakes are a four piston design which at first glance seem very similar to those manufactured by Grimeca. A little research reveals that SRAM discs are in fact made by the Italian manufacturer and they are virtually identical to Grimeca systems 8s
| I’m a big fan of this design and I’ve
been using Shimano’s XT version for about two years, with absolutely
no failures or regrets. The Shimanos are exactly the same design but they
operate using mineral oil instead of brake fluid. |

| SRAM managed to integrate a seven-inch rotor
up front by using a caliper designed for the rear. A six-inch rotor was
provided for the rear. |

| When I first began using this set-up I had my share of problems. I’d have to realign and re-shim the calipers after every wheel removal. Here is a tech tip for this problem: Once the calipers are properly centred, and the rotors spin freely with no brake rub, put a small dab of white paint on each outer axle nut at the highest point (or the centre when looking down). If you ensure these marks are in the same position when you reinstall your wheel your rotor will not rub. |

| Out on the trail the levers have a firm feel with good modulation. They do however require some muscle to get them to lock up, especially for one finger braking. I always felt confident and under control when riding with the SRAMs. They never made noise or showed any signs of fading, and they seemed to get better after a few rides (or was I just that I was getting used to them?). |

If I were in the market today for new brakes my first choices would still have to be Shimano or Hayes, because they are proven on the Shore and ridden by the pros. These brands are also well supported (parts and service) by your L.B.S. Despite this I can easily recommend the SRAMs over any mechanical disc brake, and if they came stock on a new bike I wouldn’t be in any hurry to swap them out. This is a very good brake.
