After experiencing repeated caliper piston seizure on our shop Lexus GX470, we designed a new brake kit to improve brake performance and reliability. Unfortunately, the original calipers are notorious for experiencing piston seizure due to the fact that caliper is made from cast iron and the pistons are made from steel – materials that easily corrode. Rather than replace with remanufactured auto store calipers (which will typically fail within a year), or expensive new calipers from the dealer, owners of Lexus GX and Toyota 4Runners now have the option of upgrading to our new 6 piston performance brakes.
Our GX front brake kit is easily on par with the venerable Brembo caliper/rotor found on top performing cars such as the Lexus ISF. This BBK utilizes Wilwoods massive Aero6, 6 piston front calipers. Unlike the cast aluminum Brembo calipers on the IS-F, the Wilwood Aero6 calipers are forged, and feature internal seals for higher temperature capability.
Please note that the color of Wilwood Aero 6 calipers we ship now is different from the photo of this product. Wilwood changed anodizing to grey from black. They claim that new anodizing has improved surface hardness. This product features include:
All components in this product kit, with the exception of the brake rotor
castings, are proudly engineered and
manufactured here in the United States of America.
