Wheel brake cylinder – BMW diagram

Callout 03 on BMW’s drawing “DRUM BRAKE-BRAKE DRUM/WHEEL BRAKE CYL.”. Open the drawing →

This is a genuine BMW wheel brake cylinder, part number 34 21 1 159 146. You will find it under Brakes (Rear wheel brake). It supersedes the older number 34 21 1 163 858, so a part carrying that number is the same part.

Fits E36 316g, 316i 1.6 and 318tds (1994–1996), compact, with the M41 or M43 engines.

BMW draws it on the Drum Brake-Brake Drum/Wheel Brake Cyl drawing. BMW's catalog calls for two of these at each place it is fitted. It weighs about 392 g (0.9 lb).

Out of stock. Request it and we will notify you when it is in stock.
