|What is the difference in performance in brakes across the Shimano range?
My bike is fitted with Shim 105 apart from the brakes, which for some reason are Tiagra. A couple of times descending I've come close to running out of brakes and spearing off into the countryside. Is this just a case of me needing to improve my judgement and technique, or would I get a noticeable increase in brake performance if I put say Ultegra brakes on my bike? Or different pads?

|All modern brakes are far, far superior to brakes that really were good enough. Your Tiagra DP's probably relate to old Campy Record sidepulls in the same way an F16 relates to a WWII Mustang.
OK. Hyperbole off.
Assuming that your brake pads are in reasonable shape and the brakes are properly adjusted, you need to improve your judgement and technique. I've had no problem with my (Tiagra equivilant) RX100 brakes on 50+ MPH descents.

|KoolStop pads might give you a significant improvement.

|Are the brakes too touchy (lock up easily) or do they not apply enough force to lock up (the rear) at all? If you can't lock up your rear wheel, then I'd suggest new pads and possibly a pass over your rims with a ScotchBrite pad. If not enough braking power is the issue, you might check that your levers are not bottoming on the bars. Every set of brakes I've ever had, starting with MAFAC Competition centerpulls back in the 60's have been able to lock up the rear wheel. Newer brakes may take less lever force and offer a bit more control, but for actual stopping power, there's something wrong if you can't slow down. It certainly could be that you just were going to fast/braked too late, but then you don't really say what coming "close to running out of brakes" means.|

I do think it is has been my technique. I can lock the brakes fine. I think my issue is setting up so I don't oversteer as much as anything else.
But I was curious if higher spec level brakes have better stopping power, or are they just light units, or both.
