If you need to replace or install a brake master cylinder, you’re going to have to “bench bleed” it before bolting the assembly to your firewall. That’s because, due to the angle at which the master cylinder sits when installed, bubbles can become trapped in an un-bled master cylinder’s fluid passages. To make matters worse,
A hydraulic clutch relies on pressurized fluid to amplify/transmit force, so whenever an air bubble gets into a closed hydraulic system, it can dramatically decrease the system’s ability to pressurize the fluid. That, in turn, can prevent the clutch from being able to fully disengage when you’re shifting gears. Note: Hydraulic clutch systems are very similar
When it comes time to add brake fluid to your brake system, you’ll do it at the master cylinder. But it’s not as simple as topping off the reservoir and calling it a day. There will usually be a “Max. Fill” line marked on the master cylinder, and it’s there for good reasons. In today’s
