G8 Front Brembo 4 Piston Caliper Brake Kit


19 reviews

This variant is currently sold out

This is a complete bolt on Brembo 4 piston caliper brake setup that adds look and stopping power at an affordable price! You get upgraded to 355mm or 14" diameter rotors. The standard G8 has cast calipers with only 298mm or 11.75" rotors, so it's a substantial difference in braking performance along with making the vehicle look much better.

If you are doing an upgrade for the G8 GT the factory 18" wheels will not work unless you use some spacers or run any 19" or larger wheel/rim and it will have the proper clearance.

I have heard from one customer say that their 19" stock G8 GT wheel did not clear the caliper. The offset is just slightly not enough where a wheel spacer would be needed for clearance.

This includes: a pair of CTS-V Brembo 4 piston front calipers, ceramic Power Stop brake pads, pin kit, cross drilled / slotted zinc coated rotors, and mounting bolts.

GM Part #89047726 & 89047727.

This is also a direct bolt on upgrade for 2010+ Camaro LT, RS, etc that has the standard non brembo brakes. These calipers, rotors, etc will bolt right on.

These are factory front calipers from 2004-07 Cadillac CTS-V, 2006-09 STS-V and the same caliper on the 2009 Pontiac G8 GXP. The GXP does have a different logo on the front of the caliper, but the caliper itself is 100% the same. This kit does require removal or modification of the stock backing plates. 

Everything you need in one package!

Everything is brand new! Not Remanned. Totally brand new!

Truly bolt on

Very simple process with the right tools. Brembos just fit under my 20 inch wheels so 19s will definitely need some spacers. Worst part of the process was bleeding the lines.

Post-Installation Review

First, the system arrived in perfect, gleaming condition and arrived faster than expected! Everything went smoothly on the install except my 19" rims did require a spacer and longer studs. It would be nice if they offered a matched spacers-and-studs kit for those needing it. Perhaps my '09 is like most G8s, but the '09 1/2 might have clearance with their rims. I expected this, so I had parts on hand. The kit is awesome and great looking and much smoother than stock, requiring a lot less pressure. They feel very strong, and I like that it's a straight upgrade to the GXP system in the '09 1/2 cars. This is an extremely good value, and of the highest quality in every piece, including the mounting hardware. I'm more than 100% satisfied! Install notes: Drilling the holes out is not difficult and only takes 30 seconds each because it's not much bigger, and aluminum; but I needed a 1/2" shank drill to use the large bit required. Pads went in easy, brakes bled quickly with less than a pint of brake fluid used. I bought the $79 bench top press at Harbor Freight and it made installing the studs much easier after heating the casters. I've been waiting for an excuse to buy it, so...

Before purchasing the product, I got in contact with one of the employee and he made sure I knew what I need for this install. I sure you that 1 inch spacers are all you are going to need to make these brakes work. By the way these are Brno brakes. Highly recommend them
