If you're an experienced brake bleeder or you just like to live dangerously you can skip to the bleed process. If your brake is currently fitted to your bike which is usually the case start by removing the wheel of the brake you wish to bleed first. Then using your needle-nosed pliers, remove the brake pad retaining pin from the caliper. Don't remove the pads just yet. Next, take your flat blade screwdriver and place it between the brake pads and twist gently, taking care not to damage the surface of your pads.
This will reset the pistons to their original position for the bleed. Now you'll need to place something between the pistons to keep them in that position throughout the bleed process. Anything of the correct size will do as long as its not a compressible object. If you don't have anything suitable find out how to make a bleed block. Set the lever so that the bleed port is at the highest point facing directly upwards.
Temporarily fix in position. Hold the syringe with the tip pointed up, tap the side of the syringe firmly to dislodge air bubbles so they rise to the top; and then, using a paper towel to cover the tip, push the air out from the syringe.
Take the other syringe and draw up mls of brake fluid from the bottle. Be sure to remove all remaining air from within the syringe as before. Remove the lever bleed port screw using the Torx screwdriver bit and set aside safely.
Screw in the syringe and threaded bleed adaptor. Close the tube clamp on the syringe tubing. Orientate the caliper so that the bleed port is facing up. Remove the caliper bleed port screw and set aside. Gently pull on the plunger of the caliper syringe to create a vacuum within the caliper.
You can secure it with a box end wrench. When all your bottles and rag are in place, open the bleed port by a quarter turn. With your bottle filled with new DOT fluid, squeeze liquid steadily into the system.
And then release. Do that several times to make sure that you eliminate all the possible air bubbles trapped inside the caliper. Watch the tube of the catch container and be on the look-out for bubbles and the color of the fluid. When that happens, you can close up the bleed port in the caliper and remove the bottle.
They are totally different animals. In fact, I'm not sure what the difference is. If it says dot 4 or 5. My test brakes avid juicy 5's have a couple seasons with 5. The only weakness so far is how much 5 likes to soak up air and get squishy.
PS i work in a bikeshop so i have to use the oil that is recomended otherwise there is no warranty. Yeah crisp is better. And warranty is an issue I hadn't considered since I buy used. It also comes down to maintenance.
You don't open shimanos for years at a time. You have to open avids at least once a year. If I could convert my elixir cr set I'd be a happier rider. ZacSmith Jun 12, at You can find this model designation on the back of your pads. The T is designed to wear longer and run quieter, but the T gives you that bite you may be looking for if you are running Primes for DH or aggressive AM riding.
T is the go-to padset for aggressive Hayes Prime usage. Then you get more pad area, and still have the advantages of the Prime modulation. I agree. I have two sets of Prime brakes and I have converted them to the T pads. Loving them with the adjustability and modulation that other brands don't seem to have. Maintenance is a very Important issue. When I see how greasy the hands of the guy in the video are, and when I compare how easy it is to bleed Avid breaks - I don't see any argument for Hayes.
I have two sets of Prime Expert brakes. I love them. Especially with the conversion to the T brake pads. These brakes have great adjustability and the best modulation of any brand out there. Other brakes are on or off and feel good on the showroom floor, but Hayes brakes are outstanding in the real world and out on the trails.
Dj-Tramp Jun 12, at Hope all the way for me. Couldn't have said it better. I wish Hope did a better job of marketing their brakes in North America -- I'm sure way more people would be using them here.
I was looking for a brake upgrade 2 years ago and I saw the video on the Hope website "bleed your Tech brakes" and was sold. Let the cat out of the bag Here is a quick video on bleeding your Dominion A4 Brakes too.
Let us know if you have any questions. Of all the brands of brakes I've owned this bleed kit is the most well thought out and put together. Hayes continues to impress me! Close menu.
