A quick question. What if i make the front and back brake rotor size all the same or very similar, will it decrease the nose diving motion while brake aka better brake feedback?

 

I doubt if it will help much with the nose diving, that's much more a center of gravity and suspension design issue. Feedback? I don't see the relationship.

 

to do with brake size, rate of deceleration or even front/rear brake bias...it has to do with brake and suspension geometry.

All modern cars have some bit of 'anti-dive' build into the from suspension geometry and brake mounting points...essentially what this does is that some of torque from the brakes -remember, the calipers are trying to arrest the moving disk rotor- is converted into a force that counters the normal tendency for the nose dive to when u mash the brakes.

It's kinda hard to explain in a short paragraph..do a search on the 'net, you'll see enough to understand what I mean. Bottom line, equalizing rotor size will do nothing except make you take a lot longer to stop because in a panic stop situation >70% of your retardation force is achieved by the front wheels. Why do u think high performance motorcycles have two rotors in front, one in the back?

 

It can't be done....60-70% of the braking in any car is done by the front brakes. That goes without saying the the wieght of the car pushing it forward.

 

If you move the front inner mounting point of the lower A arm downward or the rear inner upward you will increase anti-dive. Is this practical? Dunno - haven't studied it on this car.

 

Thanx guys for the informative replies, sure helps me learn as a newbie.

 

I'm pretty sure we don't have A-arms in the rear... (that was just a smartass remark)

Anyway the easiest way to reduce dive on braking is to get stiffer springs and shocks.
