Brakes: Rotors

Whats the difference between floating rotors and solid rotors?

What is the max size you guys think we should go with rotors? Using 17" mags....

Solid and floating calipers, I would hate it if my rotors floated 😂 .

I have Z32 calipers with 335mm rotors under 17inch mags, there is only about 5mm clearance though.

Sadly they are floating calipers...

Serious race cars use fixed calipers exclusively whenever allowed by the rules.

Manufacturers like floating calipers because they are much cheaper to manufacture, and their lack of positive location is actually a plus in a production application. The ability to float makes these calipers very forgiving of caliper misalignment and/or rotor run out. The downside is crummy pedal feel, as everything moves around and you have to take up the slack. This does not lead to linear brake application, and makes it much harder to keep the brakes on the edge of lockup - which is why you need ABS with floating calipers.

The only functional disadvantage to fixed calipers, be they 2, 4, or 6 piston is that they are very intolerant of caliper misalignment and/or rotor run out. This means that in many cases you will have to shim the caliper and shim and/or true the rotor. What you will get is rock solid pedal with almost no travel. This allows you to "squeeze" the pedal and modulate the brake pressure in a very linear fashion. If you can't effect maximum, edge of traction braking with a properly set up fixed caliper brake system with no ABS, you probably should be playing golf instead.

You do get floating discs, look at a superbikes front, you get the center of the disc then there are floating dowels that keep the disc itself attached, but allow a minute amount of sideways movement.

Anyone wanna attempt to explain monoblock calipers?

3300sx20 Jun 2008, 11:48

floating discs are much more resistant to warping, as far as i know..

Yip, your right Sokar, wnet and did some P.I work (private investigation)

You even get floating rotors for our nice 200sx cars..... hehehehe

If you follow Formula One, NASCAR, World Sports Car, Champ or IndyCar racing, the winning teams employ calipers machined from one piece of exotic aluminum alloy. These calipers are referred to as MonoBlock units.
