Thanks everyone.

It's Bill's WX3 rear brake upgrade kit and knowledge that made the difference. Bill was very supportive during the build and my countless emails and questions.

P.S. I wish my brake lines looked that nice, or my entire rear end for that matter.

Very nice set up, going on a very nice ride.

Zach,

Thanks! The rear axle housing was the only original part that was reused during the build and it was media blasted and powdercoated. Everything else was new including new stainless steel hard brake lines.

Also, I patterned the rebuild off of a photo that HuSSker sent me of his rear axle build by RMCR.

How is the brake proportioning with this rear kit and stock fronts? How would it be with the.. HD12 (is that the correct reference) front brake kit?

Stock & HD12 use the same front caliper piston size (area), just different caliper body casting width.

The smaller piston area of the C5/C6 rear caliper will provide slightly firmer pedal than the OE disc/disc system, but shifts bias forward, so it is definitely recommended to use the combination valve modification(s)--"stealth" bolt and/or metering plug--in conjunction with this F/R package.

The rear C5/C6 (standard or Z51) rotors are both larger in diameter than the OE rear rotor, so the clamping point is at a slightly larger diameter, for greater potential brake torque (longer lever).

The really good things about the C5/C6 rear brake setup are the much wider choice of pads, a wide range of rotors (all have to be modified for pattern and hub center size), and the much more substantial rotor mass and superior ventilation compared to the OE B-body disc setup.

I hope your car is still staying as clean as the picture shows--it IS a challenge!

Bill,

I briefly met you in person when you were our ISSCA Club President.
At our 2005 ISSCA Mountain Madness Nationals at the Pocono Speedway in Pennsylvania.

Thank you for the Compliment on my Impala SS.
After 45,000 miles of daily driving and three winters of rock salt being thrown at it.
I retired the SS from daily driving before the Winter of 98.

Mainly to save it from the 5 damaging months of Northeast Winter Rust.

Gene,

Good question--you have a number of options.

First, the understanding of "upgrade" has to be clarified. Here's my take.

The HD12 front kit is 100% bolt-on, provides greater rotor mass as it's prime feature. You can read more in the link. It will clear a 15" spare, if that is a concern.

Going with larger (diameter) front brakes than HD12 gets into knuckle modifications--it's no longer a simple bolt-on, but the changes aren't THAT difficult, just that some don't want to cut on a critical part like the steering knuckle (aka spindle).

There are several suppliers offering "big brake" packages for the front--typically, the Impala SS 17" wheel is the minimum needed to clear any of these kits--depending on rotor size selected:

KORE3 (primarily based on C5/C6 Corette OE parts)

TCE (custom kits using Wilwood calipers)

Baer (used to be C5 based, now have their own calipers)

SSBC (several different approaches--bolt-on calipers to stock rotors--not a true "upgrade"--and complete big-brake kits with their own caliper package)

Certainly the WRDC kit will still work with stock front brakes. You should at least plan to make the combination valve modifications (stealth bolt at least), if you do the disc conversion, to make the rear brakes do their share of the work.

Quite a bit of stuff, actually....

2 C5 or C6 rear calipers—available in black or red--and now, raw aluminum, like B-body rear calipers

2 new backing plates modified for this upgrade OR exchange/modification of your backing plates.

2 new caliper mounting brackets, slide pins, boots, and fasteners

Caliper mounting bracket adapters, spacers, and fasteners

Park brake components assembled to backing plates (new)

Brake pads—OE (and ACDelco)--using Corvette brakes offers a wide choice of pads from PFC, Hawk, EBC, Satisfied, and a number of other brands—FMSI D732 spec, including semi-metallic, carbon-metallic, and ceramic friction materials.

All necessary hardware, gaskets, boots, fasteners, guide pin lubricant included.

Gear lube/additive and brake fluid not supplied with kit.

THICKER C-CLIPS FOR AXLE RETENTION & REDUCED AXLE END-PLAY are available.

Additional components are required for a full drum-to-disc conversions.


I've not updated this thread, since it's no longer accessible by me (unless Dilbert 9C1 gives me access to it) and I haven't re-posted it myself.

Note that rotors are not listed here--they come from KORE3, pre-machined to fit B-body (5x5) pattern and clearanced for the disc brake backing plate.

Clarifications (this is an upgrade for existing disc brake sedans):

Default pads are OE spec, with pad delete option.

Calipers are OE finish--black/gray is standard, Z06 red is optional, will be added cost in future.

Caliper brackets are modified for the application, and the adapter brackets are offered in 2 versions, for 12" or 13" rotors.

New caliper hoses are not required, but available--including braided stainless hoses.

This kit is for SEDANS, and is not compatible with Fleetwood 4-channel ABS axles.

I may be wrong but in the pictures it looks like has has 2 left side rotors.
Looks like the vanes on the rotor on the right axle are arcing forward at the 12 O'clock position. They should be arcing rearward like on the left side.
