Re: rear brake piston size Reply #2 – October 26, 2026, 04:31:16 PM If you mean the rear brake calipers, 38 mm looks to be the correct size for some versions of the 1989 Golf GTI 8V. However, I wouldn’t assume it’s correct without checking which brake calipers you have, as the piston size depends on the brake system fitted. It’s best to measure the old piston or check the caliper manufacturer and part number before ordering.You can check the available pistons on https://www.autodoc.co.uk/car-parts/piston-brake-caliper-15094/vw/golf/golf-ii-19e-1g1/1648-1-8-gti-g60-syncro
