Information
Synchro Brake Band 1st Gear.
Manual transmission Synchro / Brake Band (Synchroniser band) engineered to match Porsche’s original specifications. Provides friction control during gear synchronisation, allowing smooth and quiet gear changes.
Fits:
Porsche 911 1974 - 1986 (915 Gearbox)
Diagram ref no 37
The synchro / brake band is part of the gearbox synchroniser system, helping to slow or control rotation of a gear or hub during shift transitions, promoting smooth engagement and preventing clash. It works in concert with the synchroniser rings, hubs, sleeves, and gearsets to align speeds of rotating parts before lock-in. Proper material, friction surface, and design are critical — the band must provide the correct friction characteristics without binding or excessive wear.
• Installation: Direct OE replacement — recommended during gearbox overhaul
• Position / Location: This part is located inside the manual transmission, within the synchroniser assembly — the mechanism that equalizes gear and shaft speeds for smooth engagement. It wraps around the synchroniser hub and works with the synchro ring and dog teeth gear to provide friction and control during shifting.
• Benefits: Restores synchroniser performance, eliminates grinding, reduces wear on gears and rings
Why replacement matters:
• With use, the original band’s friction surfaces can glaze, wear, or lose consistency, impairing its ability to slow or stabilise gear/hub motion during shifting.
• A worn or ineffective brake / synchro band can result in grinding gears, missed shifts, or gear clash, especially under load or during aggressive shifting.
• Installing a high-quality replacement restores proper friction behaviour, enabling smooth engagement, reducing wear on adjacent synchroniser elements, and extending transmission life.
• Because the transmission internals are sensitive to mismatches or degraded components, having a reliable replacement band ensures system integrity and maintains the “feel” of the gearbox.
