Whats the best brake upgrade when using stock spindle?

[Zone_4_Lanlord]

I have already bought brand new spindles, so i do not want to have to buy them again to do blazer upgrade.
With that being said, which direction should i go when upgrading front brakes using the stock spindle. Minimum rim size will not be a problem, i have big wheels.

Stock, unmodified stock spindle?

Larger brakes than 10.5" require the stock spindle to be modified (cut off the caliper brackets, drill/tap the Dust shield holes for larger bracket bolts)

Wilwood sells a lightweight dual piston D154 Caliper that would be a good upgrade over the stock Cast iron caliper.

Easiest to install on stock spindles would be oversized piston calipers. While aluminum calipers do weigh less they also flex more than cast iron calipers, its a trade off.

Best? Wilwood 140-12299-D FNSL6R​

Best bang for the buck.

The Wilwood dual piston aluminum caliper has a smaller piston area, so the clamping forces are less. There is not much of a weight difference between this and a Wilwood oversized 2.75" piston caliper.

The Wilwood oversized 2.75" piston caliper has a larger piston area, so it should give you better clamping forces.

IMO, the biggest downfall is the rotor diameter, so if you are going to spend money, spend it on a total aftermarket system that uses a stock spindle.

If you are going to keep the stock front rotors, go with good aftermarket pads first and just replacement calipers. Upgrade to stainless steel braided flex lines front and rear. If you are keeping the vacuum boosted system, upgrade with the b-body 12" dual diaphragm vacuum booster and a right hand drive 2000 S10 1.0" bore master cylinder (must be a right hand drive S10)

NEW MASTER CYLINDER OPTION

This master bolts right in no mods and actually works AC DELCO Master Cylinder Part # 89056529 or 18M974 (same master)

B body brake booster/master

Im doing the booster upgrade this weekend and was wondering about the master cylinder as well.I will be running ls1 brakes out back and c5 corvette brakes up front, would that master cylinder be a worth while swap?What about the proportioning vavle? Do the B bodies have one? If so would ...

B-Body Dual Diaphram Brake Booster Upgrade

If you're like me, you've hated the feel of your stock brakes from day one. In my case, it literally was on day one, driving the SS right off the dealer lot in 1986. I even returned the car and complained, but was told "it's normal". The pedal has an extremely soft fee...

Good pads, new rubber lines or stainless steel braided flex lines, and a fluid flush will make a big difference. Going to the B-body booster and S10 master cylinder will make it better.

You've kinda cornered yourself with options because of the stock spindles.

Wilwood doesn't make much of anything that is junk, so I'd assume their oversized D154 or dual piston D154 calipers would be your best bet, but they aren't what I consider cheap at $400 or so. Considering that you can do a Blazer upgrade for the same money, rub another $2-300 together and have C5/C6 stuff.

Mac, how much better are these than stock? This the 1st time I've seen either of these. As you mentioned, the Afco's with a good set of pads look like a $250-300 option and the Wilwood's are an additional $150. Both are cheaper than Blazer spindles if the hubs, pads, calipers and rotors are needed if the spindles are free.

 

[Macguyver]

The Afco calipers will give you about 30% more clamping force over stock. Use an aggressive pad and house rotor and just replace rotors as needed, "free if bought local using 2 years rotors". The limitation is obviously the the leverage of a small rotor. The Wilwood 14"setup is about $1800. Can do a 14" Corvette setup much cheaper. I'm off till Monday so call if you need to talk more in detail.

I was hoping i could piece together something similar to the blazer upgrade and use corvette rotors and calipers and still use the stock spindle. i would love to have the big rotors.

You can buy a kit for the stock spindle, but no piecing together. And the kits are not cheap unfortunately.
