Synlubes Posted August 28, 2002 Share Posted August 28, 2002 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!

Guest scca Posted August 28, 2002 Share Posted August 28, 2002 save yourself some grief and do a search here first.. IMO your way off base.. theres lots here about that already so search first Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted August 28, 2002 Share Posted August 28, 2002 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) Quote Link to comment Share on other sites More sharing options...
Dan Baldwin Posted August 28, 2002 Share Posted August 28, 2002 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. Quote Link to comment Share on other sites More sharing options...
blueovalz Posted August 28, 2002 Share Posted August 28, 2002 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.
