Replacing hydraulic brake lines
Quote | Reply
I have a P5 with Magura hydraulic brakes and wondering if the brake lines and oil need to be replaced every few years?

I've been bleeding them once or twice a season but wondering about a system overhaul.

I'd inspect the lines (at least what you can see- not much) and fluid.

At most you might have to flush the fluid and replace it. Can't hurt after a couple of seasons.

I'd only worry about replacing a line if it damaged, but that's pretty unlikely on your bike with internal routing.

Suffer Well.

They use mineral oil so the system doesn't suck up water from it's surrounds like DOT fluid.
Because of this the only time you need to do anything is when the fluid shows obvious contamination from parts wear or a little water has made it's way past the caliper seals.

Due to damaging a lever I've just taken mine apart after a couple of years.

Hose itself is fine - I will replace it because I've had to chop the olives off and its short, but I wouldn't worry about doing it as routine - if its not leaking then I'd just leave as is.
