This banjo bolt is used to connect a brake line (via a banjo fitting) to the dual-circuit master cylinder on classic Porsche models. It fastens the brake line banjo fitting to the master cylinder and provides the internal fluid passage needed for brake hydraulic flow. A sound banjo-bolt connection supports firm pedal feel and dependable braking performance.

Installed at the master cylinder brake outlet, the banjo bolt clamps the banjo fitting in place and allows brake fluid to pass through its drilled channels under pressure. Because it sits in a high-pressure circuit, correct fit and condition are essential for leak-free operation.
Old banjo bolts can corrode, round off, or suffer sealing-surface wear, which increases the risk of brake fluid leaks and loss of hydraulic pressure. Replacing with a fresh bolt helps restore a secure connection and supports safe, reliable braking.
When to replace:
• Brake fluid seepage around the banjo fitting/master cylinder
• Corrosion, damaged threads, or rounded bolt head
• During master cylinder replacement or brake line refurbishment
• When rebuilding a classic brake system using new lines/fittings
