Q: Have a brake fluid leak from a part under master cylinder, where lines from m-cylinder connect to.

asked by on September 18, 2016

I am able to clearly see fluid leaking from this part. The 2 lines coming off m-cylinder connect to it and it is about a foot or so below. It looks like it may be white plastic underneath with a rubber boot (similar to an axle boot) that appears separated or torn from plastic exposing white plastic underneath. I would like to know what this part is named and how common or uncommon it is for this part to fail and how hard it is to replace.

My car has 104000 miles.
My car has an automatic transmission.
