BMW Brake Master Cylinders

The brake master cylinder is responsible for distributing fluid from the reservoir to the front and rear brake systems. The fluid reservoir actually sits on top of the master cylinder with hard metal brake lines running out of it. There are a few places where the master cylinder can leak and cause a spongy or soft brake pedal. The inside has several pistons with o-rings and seals that can fail and allow brake fluid to escape. Likewise, the external metal lines also have o-rings where fluid can seep out or let air/moisture in.

When swapping an M5X engine into your E30, interference between the intake manifold and brake booster-mounted reservoir is a common problem. Tighter clearance necessitates the use of a different brake booster, which means the brake fluid reservoir will need to be retrofitted or relocated. This is particularly difficult when using the larger, dual-diaphragm brake booster from an E32 or E34.

To solve this issue, we've designed a clean, OE-style solution that requires zero fabrication. Our stainless steel bracket relocates the brake fluid reservoir to the original, left-hand strut tower location, once used for mounting the M20's power steering fluid reservoir. This provides the clearance necessary for fitting an M50/S50, M52/S52, M54, or S54 in the engine bay of your E30.

Designed with the DIY E30 24V swap community in mind, our design delivers factory-quality fit and finish with none of the guesswork.
