Default Brake caliper upgrade - make a difference?

I recently upgraded my brakes - everything but the calipers. They're still pretty soft tho. Normal driving conditions, I can anticipate stops, but if anyone cuts me off, there's no way I'm going to be able to stop in time. Would replacing the calipers (heavy duty) make that much of a difference?

im not sure how much more HD you can get with the H2 brakes...

i know there are big brake kits out there.. but they come with a big price tag too..

like starting at 5k for the brembo, willwood an such..

i upgraded my front brakes and rotors to EBC. i have the slotted and dimpled rotors with EBC yellow stuff pads.

i plan on doing the same to my rear brakes at a later time.

right now i have some issues with my TC/EBS system.. so i am able to fully lock up all tires when i need to brake hard.. and i have done it a couple of time... amazing how fast the H2 will stop with all 4 tires locked up.

I recently upgraded to AP Racing clippers and rotors. 6 piston calipers with 16 inch rotors in front. 4 piston calipers with 15 inch rotors in the rear. HUGE difference! I work for a boat dealership, so I had these installed for towing purposes as much as safety, and the ease of stopping while towing a boat is vastly improved. Plus, they fill up the 22 inch wheels nicely. Also, if u do any off-roading or driving in the sand, go with slotted rotors as cross-drilled can fill up with mud/sand.

I have pictures, but I've been too lazy to post.

I was curious how your brake upgrade went.

I do have an extra front set of the brembo big brake kit, used. 6 piston capilers, two piece rotors, red powdercoat.

If your interested, you can PM me an offer. Note nothing on these brakes are "cheap"...but the components far outlast the stock parts.

Any of the brake kits you look at now will not just bolt on. You will have to do some grinding on the spindles. How much depends on how much more material your lifted spindles have as compared to stock. I can't find a before pic of my spindle, but this shows how much I ended up grinding off.



I'm sure your steering sucks at low speed. If you get a high pressure powersteering pump, you will get back some more braking/pedal. I'd call AGR for this. http://www.agrperformance.com/ I"d get all the optional upgrades on the pump.

MUD does the steering pump affect the braking? Honestly didn't know that.
How?

Yea...the H2s have hydroboost- that powers your steering and brakes. May god be with you if you ever blow your steering pump and have to make an emergency stop. I think a freight train could stop sooner.

I snapped the shaft on my pump clean in half raising hell in the snow one night. It is very easy to do...all it takes is full crank on the steering wheel and jabbing on the brakes hard at the same time...wasn't more than 1 or 2 seconds of high resistance against my wheels and applying the brakes.

My new AGR pump was built w/ chromemoly shaft, so i'll never snap that damn thing again.

How can they get locked up with an ABS system in place? Did you disable the ABS system for the bigger brakes??
