First time poster. Newbie MTB(e, don’t judge). Need some help.
I do some serious elevation rides. Often 500-1000m+ elevation climbs (and then down we go). Coming down the hill today, my back brake got super spoungey – lost like 80% of its power – and was pulling all the way to handle bar on the lever. Not good. It came back and started working again later in the ride, then died again.
I’m thinking air in the brake line ? It got a service like 3-4 mths ago. So I’m a bit confused.
Or for this type of elevation and decent are the trek rail 5 brakes just not up to it? (Don’t really want to buy new brakes, but can’t not have confidence and not make a corner).
Also random video of my strava ride replay cause posts suck with a pic or video 🙂
Trek Rail 5 – brake failure / air ? Need advice

Brakes getting hot can cause the fluid to boil and brakes getting spongy. Smarter folk than me will likely give you ways to improve that.
The vid blows my mind. I ride 15 to 20 miles regularly. The vid looks like an epically long ride to me but the math says 23 miles. I had no idea I was riding that far. Mostly flat within 500ft incline over all. Cool to see your run.
Which pads are you running? Non-metallic pads will do that.
