In this tutorial we’ll learn how to bleed the hydraulic brake system on Tektro Auriga Comp Disc Brakes. You should always bleed the system after shortening or replacing the hose, or if you have opened the system to air at any time. If your brake action feels spongy, bleeding the system will also improve performance.
For this job you will need a 2, 3 and 4mm allen wrench, a 7mm open end wrench, a T15 Torx wrench, a piston holder or 10mm allen wrench in order to keep the pistons in place, a small bag and elastic band, and a clean rag. You will also need a Tektro hydraulic disc brake service kit, which should include a syringe, 2 lengths of plastic tubing, an outlet valve, and a bottle of Tektro hydraulic brake fluid (mineral oil). Make sure to use the specific type of oil for this brand, as using other types could damage your system. A repair stand and clean work space are also highly recommended.
Mount your bike in the repair stand, making sure the wheel axles are parallel with the floor. Now remove your wheel. Remove the disc brake pads and slide a piston block or 10mm allen wrench into the gap to keep the pistons in place.
Remove the rubber cover from the bleed outlet valve on the brake caliper. Attach the smaller tube from your service kit onto the syringe and fill your syringe about halfway with oil. Now firmly insert the syringe and tube onto the bleed outlet valve.
Using your 4mm allen wrench, slightly loosen the brake lever bracket until it rotates on the handlebar. Loosen and move the shifter out of the way if needed. Rotate the brake lever so that the top of the reservoir tank is parallel with the ground.
Using your T15 Torx wrench, loosen and remove the bolt on top of the reservoir tank, and thread the outlet valve into the hole, with the longer plastic tube firmly attached and place the other end into your plastic bag and keep it in place with an elastic band.
Now open the outlet valve on the caliper slightly 1/8 to 1/4 turn. Using the syringe, push and pull the oil back and forth through the system several times until there are no more air bubbles coming out of either end. Now tighten the bleed valve with your 7mm spanner to 4-6Nm.
Remove the hose and reinstall the rubber outlet valve cover. Now remove the outlet valve from the reservoir and reinstall the bolt using your T15 Torx wrench. Tighten this bolt to 2-4Nm.
Use a clean rag to wipe any excess oil off the lever, caliper, and hose. Reinstall your brake pads and front wheel. Depress the brake lever a few times, to ensure the action feels stiff and not spongy.
In our next tutorial we will take a more in-depth look at replacing and adjusting the brake pads on this model.
Did a search and didn't see any info on it... have any of you guys ever tried this tool ?
I like the tool... it even sets the proper toe in and adjustment. The only thing I find troubling about it, is the lip on the top of the tool keeps the pads from going high enough on the outside edge of the rim. The pads run closer to the inside edge near the spokes(see pic)(Is this the proper position for the shoes or should it be higher ?) Other than that, it seems to be a great tool.
What do you guys think about it ??... Read more >>
My original set of rear pads prematurely expired due to crooked wear on the outside pad. Upon closer inspection I see the piston extends at an angle, or crooked. This is not how the front brake extends (same model). Anyone know if opening the caliper to address this is possible? Thanks... Read more >>

Picked up some strong mtb(36h,dw) disc and rim brake compatible wheels for a great price. Was looking to convert my mtb from v-brake to disc(frame and fork have the mounts for disc brakes).
Been looking at some mechanical knockoff Avid BB5, BB7 disc brake kits that come with what is in the pic.
Anyone know anything about these? Will they work?
From what I can tell, they are just like the brand name stuff, just don't have the brand name branded on them.
Have not had any experience with disc brakes and I'm looking to try some out. If there is a better br... Read more >>
Bought some new wheels(36h, DW) for the MTB to replace the old beat up original wheels(32h) that my MTB came with. The original wheels had the machined V-brake rim surface for the brake shoes to rub on. The new set has a painted brake rim surface and the brake pads are leaving black marks on the rims. They also are making a lot of noise when braking(shoes have been toe'd in too).
Should I be using a different type brake shoe with the painted rims??

Hello, I bought a bike the other day simply for getting from a to b. It was second hand with a back flat, no biggie. However the back breaks, when I pulled them they don't seem to spring back out for the wheel to turn, so I was fiddling about with it and made it a little better but then I noticed the break cable by the handle bars have come out of its mount, the wire is still in the lever but there is no tension.
Could someone help me with this? Tried looking on the Internet but can't see any clear videos or information about fixing it. thank you!... Read more >>
where can I get the best price and decent equipment for an XR200 front disc brake???All that is there is an old stretched cable and the disc. I am a golf course rider....... Read more >>
Fixing up a vintage Gitane and just tried putting new brake levers on the handlebars. I realized that the opening where the cable is supposed to come out of each lever doesn't match up with the hole in the handlebars. Is this going to be a major problem to find levers that will fit this particular handlebar? Should I just replace the handlebar? Any help would be appreciated!... Read more >>
I'm trying to fix up an older bike. The brake cant on the front tire, right side is way off. It's already destroyed the break pad. I need to figure out how to change the cant, or any new brake pads I install will be destroyed in similar fashion. How exactly do you do this?

Hello today whilst riding my bike i lost concentration (stupid i know) im only am amateur though :/ anyways i hit a wall with the right side of the bike and my right which is the front brake snapped off.

I only just bought the bike a week ago from halfords its a mountain bike and really cheap. Any help would be appreciated.... Read more >>
Having a problem with my front break line, whenever the I steer the handlebars right too much, the brake line comes out of the mount at the front of the frame. The tension of the wire is not tight enough and i've tried pulling it through more at the brake end to no avail. I don't feel i'm experienced enough with bikes to know what to do and so thought I would ask for some advice on here. If I'm not being specific enough or you need more info. to help me please let me know.
Thanks.... Read more >>
I do lots of home and car repair but never done anything on bikes besides basic cleaning. Found a couple of stolen and abandoned bikes no one has claimed and would like to fix them up to give to kids in need.
This bike had super worn and uneven pads so I replaced them. The rear brake feels loose/little resistance when you pull the handle, although it closes. It doesn't open evenly. As you look at in the pic, the L side stays closed and the R opens a little. Of course the pads I replaced were way super worn on the L a... Read more >>
I replaced the forks on my Trek 4300 for some First Air forks just a couple of days ago. I did the same with my trek 4500 a couple of months ago with no issues.
This time I cannot seem adjust the wheel or the actual disc brake unit correctly. No matter how many times I have tried, the pads still rub ( only lightly but annoying) on the disc. When I am free wheeling there is no noise but when I move the steering erratically, it is much worse. any ideas why this may be? Are the wheel bearing on their way out?
Any help will be greatly appreciated.

So today I bought all the necessary equipment to do a 700c conversion on my Falcon Majorca. Unfortunately the Shimano 105 brake calipers that are on the bike aren't long enough so they are to be replaced with a set of Tektro long reach calipers. I really like the 105's. They are responsive and stop the bike well and I'll be sorry to seenthem go......but do they have to?
I have another bike, a 2013 Carrera Vanquish that currently sports Tektro short reach calipers. I guess my question is this; in the grand scheme of things is it worthwhile swapping the 105's onto t... Read more >>
I decided to clean my front disk brake pads by heating them. Instead of sticking them in the oven, I took the medieval approach and threw them into a pile of glowing charcoal. Apparently not a good idea, it took just a few minutes to completely turnoff the pads leaving the bare metal plates.
LOL.. off to my LBS to get replacements.... Read more >>
