brake pedal leak

Had a drip on my floor mat looked under seems to be coming from a plastic piece attached to the cyclinder at the top of the brake pedal mount. Any ideas

It is the hydroboost....I had the same thing and got it replaced. It is a common problem. If you are under warranty, get it fixed, if not keep an eye on it and watch your fluid level. The hydroboost controls both your steering pump and brakes. If it fails, you're screwed. However, they do not fail often, they just leak.

It's not brake fluid leaking its more like hydraulic fluid. I did a quick search I guess others that had this issue said its to do with the mechanism that controls the power pedals. Ill just keep and eye on it. Could it be hydro boost or would it be brake fluid that's would be leaking then

If it is the hydro boost leaking it will be power steering fluid. Master cylinder will be brake fluid.

I'm thinking its from the power pedals. The fluid is not power steering or brake fluid.

The adjustable pedals move by an electric motor. No fluid involved. Your leak is coming from something else.

Something about the lithium grease from brake pedal melting on hot days if the seal is bad it will drip. It does look like grease that's been heated up. It's forsure not brake or steering fluid. Either way its odd. My power steering fluid I change lots it gets burnt very quickly
