Axle Breather Bolt, Front/Rear Brake Hose Retainer, 66-77 Bronco SKU: 8668
Axle Breather Bolt, Front/Rear Brake Hose Retainer, 66-77 Bronco
Product Overview:
The Axle Breather Bolt plays a vital role in your Bronco’s drivetrain. As your axles heat up during use, internal pressure builds up. Without proper ventilation, this pressure can blow out axle seals and lead to fluid leaks or premature bearing wear. This bolt allows air to escape through a breather port, while also securing the center brake hose in place on both front and rear axles. Whether you’re swapping brake lines or rebuilding your axles, this dual-function bolt is a must for keeping things vented, sealed, and secure.
Sold individually—add two to your cart for a complete front and rear setup.
