Caliper upgrade

Locking your tires up is not the test of good brakes. Good brakes should be able to take your tires right before the point of locking up and hold them there.

Is that the job of the calipers, or of a proportioning valve of some sorts to get that?
 
With these old rigs it is the driver that gets you there. Knowing how much brake can be applied before the tires lock up.

The technical term or possibly what we used to call it is threshold braking learning your brakes well enough to prevent lockup but have maximum braking freaking hard to do right

Takes some experience and honestly, how many of us practice that? That's why they invented antilock brakes.
 
I definitely agree, you have to drive these trucks. No sleeping at the wheel or you are gone.
 
I want to be at Bens house when he burns out, and all of this trick stuff is for sale at 10 cents on the dollar.

Soory Ben. Could not help myself.

It takes the whole system (including the driver). The dual, quad, or 6 piston calipers do more than just increase clamping force. They spread the load more evenly across the pads. Look at how little surface contact the piston actually has with the pads on our stock calipers. Compare that to these Willwood calipers. I would bet that they release more completely as well so you don't have as much static drag on the brakes when the pedal is not pressed.

This is all true.

The release part is a touchy thing, we actually run 2lb residual valves to keep the pads in closer to the rotor to decrease pedal travel.

OEM or OEM reman stuff is just ok, caliper flex, load spread, contact area etc are not optimized like the nicer aftermarket calipers. Does your average everyday chevy truck need $600/corner calipers NO. Would you like them if you had them YES.
 
This is exactly what I am looking at doing. If you find any kind of stock replacement parts for a larger /caliper/rotor let me know.

I'm on board with the D52s as of right now with some slotted rotors.
 
I wonder if there IS a stock application out there that will bolt in place of our calipers that are dual piston :thinking: .... It seems that there would be SOME where.... I have something new to search the interwebs for:waytogo:
 
BTW, if you're interested I have an extra set of rear disc conversion brackets with hardware I need to sell if you want to upgrade your 10/12 bolt axle. All it needs is rotors, calipers and soft lines.
 
Upgraded calipers would be sweet.

That being said, most people look to upgrade their stock systems cause they aren't setup right, they are old and messed up, not properly maintained, etc.

I've been through the whole braking system in my truck, and i'm happy with the results.

Get NEW stock calipers, lube the slides with high temp silicon based grease, and regrease ever other other oil change, and every time you have the front wheels off.

Keep your rears properly adjusted. This makes the biggest difference.

With stock front calipers, and 14FF rear drums on my burb, i've never really had the desire for stronger brakes.
 
mine needs a total redo.... im in the process of getting parts now. they suck..... but I figured if im gonna buy the parts... why not look for better stock bolt in's :dunno:

Eh. I love that idea, but at $15 ea vs 300, the stocks do fine for me.
 
The 1 ton Burb calipers are a bolt on for the half and 3/4 ton trucks and feature a slightly larger piston, those may be worth a look for an upgrade.
