Question

[websurfer970]

I think the primary purpose for four wheel disk would be show purposes. I disc brake looks much nicer than a drum no matter how its painted.

i like them because i have them

the show element of 4 disks is a lot nicer. the rear drums do brake better, but i plan on a full KVR python brake package with 6 piston fronts and 4 piston rears. ( 2 years till i have that kind of money)

I'd have to disagree with that comment. OUR cars drums do better. Like I said look at the tiny surface area of the brake pad. Look at the tiny piston in the caliper.
Is only slightly bigger than the size of the inner bore of a drum brake wheel cylinder.
And the drum brake wheel cylinder has 2 pistons as opposed to one. However Most other cars have larger pistons in the caliper. I'm sure you know hydraulic principle well enough. Yes there is more surface area on drum brake shoes, but assuming you've got a decent sized (bigger than the one that we've got) piston in your caliper you will get more clamping force.

two words:

traction limited



will this STUPID discussion ever end?

[midnightblue97]

its possible.

As mentioned, rear drums do have more stopping power. It has to do with the geometry of direction in which the frictional force is applied.

Disc brakes cool a lot better, which is why they are better for racing applications.

??? cooling. given the right knowlege you can cool anything. the 4 disk have the most _potential_ ie upgrade.

ok stock purposes, if you have rear drums keep them unless you are serious about racing. if you do upgrade to 4 disk, upgrade because you have plans for a bigger brakeing system. and yes your braking system is limited to the traction of your rubber. wheel lock up is wheel lock up no matter how much more force you apply. it is called force equlibrium. if sigma F of (m) = 0 then that is your brake point you exceed that hello lock up, and skidding.
