Title: 86 scottsdale brake code
Post by: muleystruck on March 31, 2019, 06:55:23 PM

hello all, my 86 Scottsdale has a 1J55 brake code on the SPID. So what does this mean? All info is greatly appreciated.

Is it a K20? Heavy duty brakes is what it means. Most likely 13" and the larger wheel cylinders, all metal master cylinder.
