Review on A Premium Brake Caliper For APBC0299 by Justin Abreu

Bought these for my 7200lb 1990 K2500 Silverado. It's not advertised but I believe it's for £8600. They have a slightly larger piston diameter than the stock piston (3.15 vs. 2.94). They put a lot more pressure on the A-pillar brake discs. So you need to upgrade your rear brake master cylinders to the 3500 Dual Dual (Raybestos wc37337) model. Now my brakes are better than ever! Is always! I can stop like never before! After many days of frustration and research, I finally figured it out.
