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.
My daughter has trouble activating hand brakes on her bike. She has small hands and she can hardly reach the handles, and the handles are too hard to pull. I saw the post on the adjustment but I was wondering if instead it would be possible to replace these terrible brakes with something better? I went to a store today and they told me that nothing better would fit the bike because it is a "price point bike". Well, I know it is a cheap bike but I have hard time believing that nothing can be done.

I am having trouble adjusting some cross top / interrupter brakes on my cross bike. The brakes are Avid BB 7's. The trouble I am having is when the cross top lever is tensioned how I like it the main lever is soft. When I tighten the main lever to how I like it the cross top is way to tight. Is this due to different pull ratios of the lever styles or am I missing something? Ideally I would have both levers at even tension. Any suggestions appreciated!

Today I replaced a shimano hangar and straddle wire brake assembly cable and sheath and was successful. What I would like to see now is a video on adjusting these type of brakes, my favorite brakes btw, to see if I missed any short cuts. I googled for a video but couldn't find one. Anyone have URL for a video on this repair?... Read more >>

I am converting a MTB with 26" wheels to 700c. I live in the UK and do not go off road, but would like a bike to ride on canal tow paths (some of which can be a "little rough". All is OK, have swooped out the front forks to a rigid type (with the correct bosses for mounting a V brake onto a 700c wheel) - but....i would prefer too fit V brakes on the rear, and the bosses are in the wrong place. I know that Mavic used to do a converter, but cannot find one anywhere. Has anyone else done this? and what did you do?
Many thanks in advance.

I'm trying to get an old Cannondale M500 mtb back rolling again. I'm missing the post that screws into the fork on each side and the back seat stay post too, so I can install some v-brakes. I'm not sure what the true name for these post are or where to find them. Anybody know... ??

I understand there are 2 types of disc brake pads either sintered (metallic) or resin (organic). I just bought some disc brake pads. How do I tell which type it is when im looking at it?
Thank you... Read more >>
Anyone know the link that's out there for replacing the recessed nut studs on tektros top end sidepull brakes (I did it on the quartz) using tektros lower end sidepull nutted studs. Believe it was a YouTube vid.
Have a friend who wants to do something similar and the link to the video would be far easier than trying to word by word the conversion.... Read more >>
My 90's road bike is working but the brake to the right is loose a little bit (from the brake sleeve or what ever that's called) it's still braking but the cable is trying to come out. How do I fix that?... Read more >>
Simple one for you. I have an Azzurri Tigre which has the gear changers intergrated into the brake levers.
What is this system referred as?
Thanks in advance for the education.

On Wife's ~1970 Gitane Grand Sport Mixte, with Mafac Racer Brakes, at the handlebar brake lever (Safety Brake levers, by the way).....
At the point where the brake cable enters the brake lever, is a cream colored plastic nipple that mates the cable shield to the brake lever assembly.. Not adjustable, just an interface from cable shield to brake assembly.....
The brake assembly does not contain plastic covers, just aluminum metal.
One cracked earlier this year, and I bought two loose pieces that look like this type:

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 >>
