Brake system

I have a Trek Marlin 5 from 2019 that I just got used, and I am a newbie to learning about how bikes work.

I can see with my own 2 eyes that it has disc brakes...but am I correct that they are not hydraulic and therefore require little to maintenance besides making sure that the wires are tight?

The bike specs are at:

If you don't see any bare wire cable when it gets to the disc caliper body, then it's likely hydraulic. TeckTRO ? Shimano?

According to this pic:


it’s a hydraulic brake.
If they were mechanical, there would be a barrel adjuster, a visible wire and a lever here.

Thank you. It's a TekTro.

Thank you. I guess I need to learn to maintain hydraulic brakes!

With luck, and good storage, it can be years before you need to do anything more than replacing pads.

Or establish a relationship with a LBS that sells Trek or another nearby shop that works on anything. For things that don't require replacement parts many LBS's are inexpensive. At least that's been my experience. A lot of the stuff I've had them do for me, I'd charge more for it I did it. Guess it's a good thing I don't own a LBS.

If you are going to DIY, then find the manufacturers documentation for servicing them.

And Park Tool has some decent videos and written info to look at.

Thanks! I am looking to learn how to do most bike maintenance myself, not to save money, but just to learn a new skill. Should be interesting.

Initially one tends to spend more cost, in $, time and reliability, as one begins to learn how to do bike maintenance. Tools cost $. Judgement is not yet well honed. Parts are sometimes damaged or negatively affected with poor techniques. Having to revisit the service job one's learning is common for beginners.

But in the long run one gets faster, better and learns their limits so the efforts have better results. Andy

That is my attitude for sure! I already stripped the threads on a cone I think and will probably be buying a new one. But it's all part of the learning process. It's not about the money for me.
