Ok. Pros: 4 pistons, larger surface area gripping, firmer grip.
cons: 280zx(direct swap) or larger diameter master needed, little bit heavier than the stock callipers, harder to get performance pads for.
Perosnally, after driving down some steep hill climb areas with my brakes, i much prefered them over the stock ones. I never got any fade and pulled up really well. But without the 280 master, they were pretty spongy, infact i found the floor once when i locked up at a roundabout.
At the time my setup was: LN106 4 pot solid rotor version, DBA slotted rotors, performance pads (unknown brand).
Now: LN106 callipers, performance pads, DBA slotted rotors, 280zx master, braded lines, rear disk conversion. Ill let you know how it goes when i get the car back on the road.
Oh and yes you do have the correct callipers, but im unsure whether you have the solid rotor or vented rotor version. The vented rotor version is a bit better in that if you want to you can convert to a vented rotor or just use a solid rotor. Obviously you cant use a vented rotor in the solid version calliper.
Also, incase anyone is looking for Hilux callipers, do not buy them through Zed dealers who put a massive price increase on them, if you look on 4wd forums, i recently got a pair for $50 for ZD44TT from www.4wdmonthly.com.au/forum
Its a shame it has to come to that too, they shoot themsleves in the foot with things like that.
