My problem is that if I step on the brakes, they work very well. It's just that they don't feel as tight as I'd like under normal to moderate braking. It's a smoothness issue. It's hard to slow down uniformly -- you can feel the brakes grab more at the beginnig of a stop then at the end. They feel as if they are heating up (brake fade).
Will the TRD pads work with the LC? Any better pads out there? How about a better/slotten rotor design?
Any other ideas to improve the brakes? The TRD big brake kit however is still out of the question I think with 18" wheels (per the TRD website, requires 20"+ wheels).
If I remember correctly, the TRD Big brake Kit brakes are 16" in diameter so you may well be able to make them work with 19" rims. 19" rims with a 33" tire, or even better a 34", would still allow a good amount of sidewall for off-roading, though this is dependent on the extent to which you rock-crawl.
They certainly won't fit on an 18" rim but the reason they say 20" only may be because, to the best of my knowledge, Toyota doesn't make a 19" rim with the correct lug pattern.
It would seem odd to have brake fade unless you are repeatedly slowing from high speeds, it sounds like more of a pedal modulation issue. Having a little more disc would help with cooling though so, as described in my last post, you may get some benefit from the .4" increase in diameter.
There's a a plethora of great aftermarket brakes but the problem is finding ones for heavier truck-like applications. Most are aimed at the sports car or sports sedan market so are cross drilled and comparatively thin which makes them unacceptable and prone to cracking on a 7,500lb vehicle especially with a 4,000- 8,500lb trailer out back.
There is a company (name escapes me) that offers 16" aftermarket brakes for the Super Duty but they're an 8-lug design but if we can make the TRD big brake kit work with 19s rather than 20s I'm sure many people would follow suit, though a 17" or 18" wheel is certainly favorable.
It'll be cheap to try the slightly larger Tundra brakes and they WILL fit with the 17s, a touch less rotational mass too if you keep the same height tires.
Good luck.
