Re: Weird hissing from the brakes!

Hello, you may have air in the brake line. If you disconnected the brake hose from the calliper when you replaced the brake pads as some people do, then you will have air in the line and will need to bleed the system. Or if the fluid dropped below the min mark in the reservoir this will also cause air to enter the line and will need to be bled. The clutch having a bit of air when you depress the pedal shouldn't fail an mot unless the clutch won't engage and drive, but this also can be bled to free any air trapped in the system. Hope this helps.
