From your link, your bike has Tekro HDC Hydraulic brakes. If you do a google search, there is a video (made by Tekro by the looks of things) which talks about how to replace pads on these brakes. I suggest you watch this video. If you understand it, and feel comfortable doing what it suggests, take the pads out and examine them. Don't buy any replacements ...

(within reason) Any disc brake will fit on any bike with the right adaptors. The adapter you need will be based on the size of the rotor (disc) you want to run, the mounts you have on the bike (IS/post) and the brake you're trying to fit. Most callipers will have post mount fittings so require a adapter to fit to any IS mounts. Most frames still have IS ...

Most likely cause if the disc and pads are contaminated. What did you wash it with? Many cleaners leave a residue. Worst case the pads need replacing. The discs should be well cleaned before installing new pads - Use a solvent such as brake cleaner, methylated spirits or Isoprop alcohol, and rub the discs to be certain no contamination is left on them. ...

There are a number of simple things you can do to try improve performance before replacing the brake pads. Check the pads to see how worn they are. Here is an example of a new and worn pad requiring replacing. If the pads don't appear to need replacing you can: Lightly sand the pad with fine sand paper Clean the rotor with isopropyl alcohol (or any ...

Though there are some very good answers here already, I get the impression you are more interested in why the brakes suddenly stopped working after you stopped riding for a moment. I am not a brakes expert, but I have a solid background in thermodynamics. From that perspective, it sounds like what happened (as explained above) is that you had boiling ...

Lets put some physics to play (mostly because I want to do some numbers....) Assume the brakes did all the work..... 200kg all up weight of rider, bike, trailer and kids. 350Meter vertical descent means you need to dissipate 700kJ of energy = 200WH. I found a reference to "Road and mountain brakes must absorb 75 watt-hours of energy over a 15-minute ...

What you experienced was brake fade. There are two reasons why it happens: The fluid inside the brake boils releasing gas into the system which makes the brakes feel spongy and then non-existant. The pad and rotor heat up sufficiently to not work, this feels like you are applying the brake but it doesn't work. You look to have experienced the first. ...

I suspect you overheated the caliper so it expanded a little causing a leak. The smell was either plastic parts of the caliper or brake fluid burning off. Once it cooled a little your pumping the lever cause the self-adjusting feature of the brake to adjust to the loss of fluid. That's what makes me think it was fluid loss rather than the caliper itself ...

When mine squeal I remove the pads, buff with some wet and dry, put them back in, and re-center the calipers. It fixes it 9 times out of 10.

There are three possible things that could be causing this: Too little mineral oil remaining in the system, did you top up the brakes after shortening them?. This would create a vacuum in the system and would prevent the lever from returning fully. *--EDIT on reflection I think this is unlikely with a Shimano brake as after oil falls below a certain level ...

You need a kit to bleed that brake. Disc Brake Bleed Kit It is one of those tools/kits that as an individual it is not worth buying. Even on Amazon the kit it $40. A (quality) bleed replaces the fluid.

Hydraulic brakes develop air in the lines as they're used ( heat / chemistry are to blame ). The only way to remove that air from the system is to properly bleed the brakes. Trying to find a shortcut around this important procedure probably won't help you any, and worse case scenario you could kill yourself or someone else when your brakes fail. With this ...
