How to bleed MTB brakes

Brake bleeding can be an intimidating bike repair, but it's actually really easy to do-much simpler than many other repairs.
Today, I'm going to show you how simple the concept actually is, and get you on track to bleed your own brakes.
According to a recent poll, about a third of you are already bleeding your own brakes, so maybe you could help answer some questions in the comment section.
Get yourself some rubber gloves (I know I wasn't wearing them). Also rags and a spray bottle for alcohol or water.
This wrench is pretty useful for working on brakes

Sram, Avid, Hayes, Hope, Elixir
Shimano, TRP

If you want to find a bleed tutorial just find the model of your brake and search for it on RSclub. The GMBN videos are great, and Performance bike also has a few good ones. When in doubt, just go straight to the manufacturer.

    hey Seth I'm from India. I have a doubt that as you have shown that we can use a syringe to bleed the brakes but can please make sure that I have to screw in the syringe or I have to just put into the lever.. please clear my doubt because I am bleeding my brakes for the first time and mine are Shimano brakes and there is no funnel for bleeding in online or offline...

    At 0:40, cars and motorbikes use hydraulic brakes because hydraulics work well with a servo. The engine can pump the hydraulic fluid to considerable pressure, then a servo takes input from the driver and amplifies that force hugely. Try this (somewhere safe) : Park your car on a gradient. Switch the engine off so that no pumps are running. Pump the brake pedal until it goes stiff. Now let the handbrake off and let the car roll. See how useless the brakes are without the engine running. That's hydraulics without servo assistance. Hydraulic without a servo is no more powerful than cable actuated. If it seems like they are, I suspect that's because hydraulics usually come with better rotors and bigger pads. It's not the hydraulics per se.

I currently have Q3 Promax and I can't find a single instructional video online, I can't even figure out how to remove the pads... I tried Bleeding, made big mess, I gave up lol. Just going to get new brakes, been riding around with just the rear for like 2 years now, I think I can splurge.

The manual for the bike is so poorly put together it does not talk about any kind of maintenance. What should I use brake fluid such as DOT 3 or mineral oil such as baby oil loool.

    shimano brakes are the easiest to bleed, you dont even need a funnel, you need brake oil (or baby oil) and a dressing bottle, fill everything into it, then drip oil into the port otherwise used for the shimano funnel

    I wish my bike shop charge $11 for each brake but NOOO they charge $35 for each brake. I rather learn how to do it myself, perhaps I bled both of my shimano brakes for $5 which was the cost of the new mineral oil

    Buying a fresh bottle of DOT for every bleed can cost as much as the bleed in the shop, and that stuff is messy. I’d rather pay the bloke in the shop. That said, I can do my mates Shimanos in 20 mins and get it right every time. When the lockdown is over I’ll see if I can accidentally smash my guides on a tree.

    Just whenever they start to feel really spongy. I don't know if this will wind up being true or not. But the people at the bike shop I went to told me I probably wouldn't have to worry about having the brakes bled for probably a few years. Plus, they gave me a nice price for having that done when I need it anyways. So I have no worries.
