Could use some brake input.....

[pderkswde17]

I think the issues mentioned earlier on and elsewhere with the brake system response (slow to start then wham, full stop) is a characteristic of the master cylinder more than that of rotors and pads. Although semi-metallic pads will offer more bite than the OEM ceramic.

Is there something to be done, as in this is a master cylinder problem needing correction, or just characteristic of a normally functioning master cylinder? Getting tired of the softness and occasionally consistent pressure on the pedal allows some forward roll after a complete stop. Brake fluid is full. Taking it in for service soon, just crossed 77k.

My brake evolution and comments...

Stock rotors and pads => no complaints (truck was much lighter in those days) but the rotors and pads needed service within 15k
Stock rotors and TRD pads => good performance but the TRD pads were noisy
Stock rotors and terrain tamer pads => better performance though the TT pads were a little noisy (not as much as TRDs) and create a lot of brake dust (not a huge deal to me, though)
Terrain tamer rotors and terrain tamer pads => best performance but still had some minor noise (to be expected with performance pads) but also a weird high-pitched squeal that led me to swap in OEM pads (more on this below)
Terrain tamer rotors and stock pads => current setup which seems to be a solid combination but I don't have as many miles on it yet

Regarding the terrain tamer pads and the squeal I mentioned, I'm likely to try out the TT pads again when the opportunity arises. The performance with a heavy truck was great but the high pitched noise was a problem that seemed to be correct by swapping pads. I'm not sure if there was something unique about the TT pads as I just haven't had enough time to try out new TT pads yet.

I have the TRD pads with DBA slotted rotors = no noise. I have been quite happy for the past 5000+ miles

I too have TRD pads w/DBA slotted and no noise (just a lot of brake dust) with just shy of 5k miles...
