二手重機必做！YAMAHA R7 DIY 更換前煞車油，找回 Brembo 直推總泵的紮實手感！

Besides changing the engine oil, the brake fluid, crucial for safety, is a top priority when servicing a used car! The YAMAHA YZF-R7 comes standard with a very generous brake configuration, featuring a Brembo direct-drive master cylinder and Yamaha's classic "Twin Star" opposed four-piston radial calipers. This golden combination offers both powerful braking force and extremely linear feel. However, if the brake fluid hasn't been changed for too long and has absorbed water and aged, even the best calipers and master cylinder won't perform to their full potential. Today, we'll guide you step-by-step on how to replace the brake fluid in the R7's Twin Star front dual-disc system and completely bleed the air! Because the front wheels have dual calipers, the bleed sequence and details are critical. The video will share how to safely remove and install the fluid reservoir, how to bleed the brakes sequentially starting from the furthest caliper, and tips on how to avoid splattering brake fluid onto the paint and rims. Want to restore your R7 to its precise, rock-hard braking feel? Take a few minutes to do it yourself and gain absolute peace of mind on mountain roads and the track – this is an essential step!
