Rear Disc


Recommended Posts

I have an early 260 and would like to use (or am thinking about) my 4 spot Toyota calipers in the rear! I need to know if there are rotors (solid) that would work in rear, with out mega modifications? Making brakets for rear calipers is not a problem, finding a rotor to slip over stub axle and have enough off set??? The 4 spot calipers w/stock, cross drilled rotors have been in use in the frt for some time! I would like to install larger, vented rotors and bigger frt calipers up front and use what I already have (calipers) in rear! OR I read here about using Maxima vented frt rotors (don`t remember year) w/ the frt vented toyota 4 spot calipers in the rear???

Any info would be great!

A few things (real quick):

Ask yourself WHY you need to do this. If you're roadracing and have enough power that you're smoking the best pads you can get and/or are boiling the fluid in the calipers, this mod *might* make *some* sense. Do you have brake problems now?

 

ALWAYS consider what you're doing to f/r braking bias. An adjustable rear prop valve can help, as well as different cf pads f/r, but the basic hydraulic ratios and working rotor radii should at least put you in the ballpark.

 

Also, consider what you'll do to braking effort/pedal travel. Bigger calipers and/or rotors means your effort at the pedal will be reduced quite a bit, but pedal travel will increase.

 

The ideal brake setup is the absolute lightest-weight setup that will never overheat.

 

Oh yeah, that's 4 POT calipers. Single piston e-brake calipers are called spot calipers.

(OK, that's REALLY nit-picking)

I screwed up *slightly* in the above post. Increased rotor size will NOT increase pedal travel, while improving braking gs/ effort at the pedal. Bigger calipers WILL increase pedal travel, while increasing braking gs/effort at the pedal.

 

Serves me right for being a smartass.

Dan, we still luv ya anyway. If you've got some really big rotors and calipers up front, the bias will not be problem that a proportioning valve can't take care of. I've got an arrangement on my Z that uses front Maxima vented rotors with front Cressida calipers (it used to be 280ZX calipers), all on the rear of my Z. It's a bit of overkill IMO (even with the racing set up and tires I had at that time) on all but the very worst tracks as far as brakes are concerned. Keep in mind though, even if this set up sounds attractive, the non-floating calipers you mention most likely will not fit due to rotor offset being designed for floaters, hence the caliper useage mentioned above.
