For the CL-S

when we apply the brakes are only the front brakes being applied?

if so what is the purpose for the rear brakes? and are there any cars that have like a four wheel braking system?

i was thinking about getting some aftermarket rotors and brake pads but ive heard a lot of people replacing the rear rotors and pads as well. Why is this?

Of course the rear brakes work, why else would they be there? :P

The fronts do more of the braking though, because of weight transfer when stopping. That's why fronts get special attention, with vented discs, bigger discs & larger calipers/pads.

 

The pads are being replaced, but the rotors are only being re-surfaced. A service manager told me that the pads which originally came with the car were getting too hot and warping the rotors. Most cars braking percentage are 70% front 30% rear. Of course that changes if the car is mid engined (NSX), or rear engined (911). As mentioned that is due to weight transfer as well as safety. The brake bias (front to rear) is adjsutable on most race cars. If you've ever watched a race and seen a car spin going into a corner it was probaly due to too much rear brake bias.

 

I beleive our brakes, like many cars, are actually tied together in a cross pattern; that is, when you activate the front right brake you are also activating the rear left and likewise when you activate the front left you are also activating the rear right.

I think the cross set-up is a 'safety' feature: if one pair goes out you still have one front and one back brake.

As the others said, the front brakes do more of the work because of the weight transfers in our car.

 

Yeap, with a brake proportioning valve. Or the cheaper way is to mix and match 'stickier' pads with less 'sticky' ones on the front and rear. That's what the MR2 racer dudes do, to move the bias to the rear (fronts lock up sooner than the rear with the same pads all the way around).

 

so

when you apply the brakes all four brakes are engaging at the same rate and pressure?

how does ABS tie in to all this?

does it pump all four brakes or only the fronts?

uh oh, more mods!
