CT4-V Girodisc brake job + general maintenance at 61K miles

[dstewart51]

Hi all, its been a while since Ive been on here. Still have my 23' 4BW and I drive the crap out of it. 61K+ miles on it now. Yesterday included an oil change, Green Air filter clean/maintenance, replaced the serpentine belt, rear diff fluid change, cabin air filter change and front brakes. I see both front struts are starting to leak and I have a bit of a clunk under rebound when the suspension is set to med stiff on the driver front. So I have a set of struts and strut mounts on order, this will be next weekends project.

I'm on the 3rd set of PS4S's and just finished the 2nd set of front pads. The rotors are smooth and warp free but they are very dished out with large lips on the edges, so I deiced for the third set of pads I'll replace the rotors. I went with the Girodisc rotors, they look fantastic and they are a bit lighter than the OEM Brembo's;
24lb 12.4oz - warn out OEM Brembo's(I suspect about of 1lb of iron warn off)
23lb 13.8oz - new Girodisc rotors

I also flushed the brake fluid, which almost lead to disaster but was averted thanks to a post I found on a Corvette forum. My bad for trying to manually bleed the brakes without first disconnecting the battery, DON'T MAKE THAT MISTAKE. I set a P25A2 code and tripped a brake module fault, which put the car in to a limp home mode with a 43mph limit and set the CEL and disabled the ESC/Anti-lock systems. The good news, it was easy to reset, just hold the start button for 20 seconds or so and press on the brake peddle nice and firm until the clicking stops, then use a scanner to clear the code. To bleed the brakes manually, just disconnect the ground on the battery with a 10mm socket first. Hope this info helps someone else should they make the same mistake.

Here are some photos, because we all know a post is worthless without photos.

Those look great!

FWIW, I used a Motive pressure bleeder to change my brake fluid without any issues. I never did touch the brake pedal though, that may be the determining factor.

Great job! Racking up the miles and throwing in some brake bling. I'm sure sharing your maintenance procedure will help someone else down the road.

Interesting....., noticed you only did the front brakes.
How were the rear?
I, along with 122 other BW owners nation wide are waiting on rear brembo brake pads.
They are backlogged apparently. I've been without my BW since nov.18th due to no rear brake pads available.
I thought I could do an end around on the OEM brake pads by purchasing BW Brembo pads from KNS.
Unfortunately, I didn't realize that, while these pads fit..., they didn't have the notch cut out in the pad for the brake sensor.
It was suggested that I just tie up these sensors to the springs up out of the way...., but I was just uncomfortable doing that.
I guess a lot of the Camaro SS 1LE's use these same pads, and a lot of folks use them to track with.
So...., I have front & rear pads from KNS for the BW & Camaro SS 1LE (brembo) if anyone is interested.
Letting them go cheap for $100 each set.
Just for the record, I have had to replace my brakes at 21,000 miles. I purchased it with 10K.
So it looks like it was run pretty hard before I purchased it, looking at the brakes and the pilots.
My stock front rotors are dished as well (very lightly) but overall smooth and warp free.
Next pad change I might switch to the GD rotors. It will probably be due new rotors by then.
You mentioned 4 sets of pilots. Did any have toe wear like the link below?
