My new bike came with Sram brakes but I just couldn't grow to love them. Played with them constantly until realizing they're never going to be what I want. Long story short, I swapped them for XT's and never looked back.
Just because a set of brakes is spongy is not a reason to replace - that is a reason to repair.Hi guys I bought a used Santa cruz Hightower that came with Sram guide r. The brakes are not performing well at the moment, the braking is spongy and not strong, the lever travel long. I was wondering if it worth to buy Sram bleeding kit and bleed them or replace with Shimano XT (i already have Shimano bleeding kit).
Can't argue with this.Just because a set of brakes is spongy is not a reason to replace - that is a reason to repair.
Now if you have always used / preferred something else, and you are looking for this as an excuse to swap to what you prefer, then yes, replace.
I agree. In fact I agree so much that I bought Saints instead of any of Shimano’s newer 4-pot models. The way my bars / controls are set up, I can’t get everything where I want it with the wider perch of the latest model lever. All my controls employ discreet clamps. I’ve never detected any flex in the old style lever among the myriad pair of Shimano brakes I’ve ridden hard over the years. But that’s just me.Side note but I prefer the older levers. Was a little disappointed with the new, wider style.
Yup. Want more power, quick & cheap? Quickest / easiest way to get it is with bigger rotors. No question.I bought M7120 SLX 4 pot brakes recently. I upgraded them to XT spec with 2 of M4x12mm grub screws which cost me precisely one dollar.
Having said that, I actually believe that the best upgrade you can do is increase rotor size. I justify this by saying that the power difference between the M7120 and my 2 pot M615 deore brakes is... noticable, but its actually not that significant.
2 pot brakes are more on/off whereas the 4 pot are more linear. Both have heaps of power.
Shimano brakes are very easy to do a quick, bad bleed job on. The full multi-step technique as documented in the dealer manuals at si.shimano.com takes time gives you a great feeling brake.
Both are way better than some M420 4-pot brakes on my wifes bike.
Agreed. My long story is that I swapped M8000’s from another bike to replace Sram RSC’s. Everything I wanted with lever feel was there but power was lacking going from 4 piston to 2. So I went 203mm up front and 180mm rear. Honestly, rotors were an excellent upgrade but still wasn’t enough until I bought M8120’s lol.Having said that, I actually believe that the best upgrade you can do is increase rotor size.
