View Full Version : Brake Calipers

Now, i know dual piston give better stopping power then single. but what if the single is larger then the dual? I assume dual is still better since its pressing on each side of the pad, rather then just the center?
i just did a basic brake job on my mom's 2000 mustang, and noticed her caliper is pretty much the same as ours, but has 2 pistons in it. Its pretty well known that we can swap calipers with other cars, but you require bigger wheels to do it (17" at least, if i remember) but are there any smaller cars that might have 2 piston brakes that would mount up on ours? (i'd love to have better braking w/o having to make a major investment like new wheels) the mustang's looked pretty damn close, but i bet there is something i'm not seeing that would prevent it.

Dual piston help distribute the force more evenly on both pads. A single piston forces the entire caliper to slide to one side. You won't get more clamping force by switching to dual. You need a higher pressure Brake Master Cylinder to get more pressure. Switching to steel braided line helps as it doe not expand as much as rubber line
A bigger piston is better than a smaller one as it distributes pressure over a larger surface. What you want to look at is the surface area the piston contact with the brake pads.
Other things to consider, brake rotor, fluid type, fixed or floating type caliper.
Hope this helped.

good info....im about to get cross drilled rotors....how does the fluid type help though if u dont mind me asking

ok.... so unless you went with the bigger brake caliper itself, then that'd make the difference, not just the dual piston. good to know.
and also steel brake lines? (i'm betting thats a negligible difference w/ the others not being done as well)

Bigger caliper generally have bigger piston or more pistons to cover a larger area on the pads, Steel braided line will yeild a very noticeable difference in brake feel. Trust me you will feel the difference.
@ alerosaint our car currently use DOT-3 fluid which has a boiling point of 401 F. I switched over to Valvoline Syn DOT-4 with a high boiling 446 F. I like to find some DOT-5.1, but those are ridiculously expensive.

it's a tight squeeze but you can fit corvette/camaro calipers and Impala rotors on stock gagt wheels. I assume our Alero wheels are somewhat similar size so they might fit?

nope, Can't fit stocker 16" I tried.

$7 for 8oz.??
and why do they say use dot 3, if dot 4/5.1 is so much better??

yea i thought about using a higher dot brake fluid but didnt know what the benifits of doing that are..
