Hydraulic bike clutches are nice in comparison with a standard cable-actuated setup. They’ve a light-weight pull, you do not have to regulate them, and they’re are extra constant feeling than some cable variations. With all that awesomeness comes just a little little bit of care past the lubing and slack adjustment required from a cable setup. This time on MC Storage we discuss altering the fluid in your hydraulic clutch.
Similar to the braking elements on a contemporary bike, a hydraulic clutch makes use of strain utilized by a lever by means of a piston within the grasp cylinder to switch that pressure to the slave cylinder. It pushes its piston out (identical to in your brake calipers) to actuate the pushrod. That strikes the strain plate, releasing the pressure holding the fiber and metal plates collectively, thereby uncoupling the transmission from the crankshaft.
Over time, you could discover that the actuation of the clutch could really feel much less constant or notchy. The fluid may get an air bubble trapped someplace within the line, but additionally hydraulic fluid will take in water from the air, which is able to ultimately result in corrosion. When this occurs the fluid turns into murky or discolored. Or it could be time in response to your guide. Both method, we’re going to change it.
Should you’ve ever flushed brake fluid, then you’re properly geared up to do that. The strategy may be very a lot the identical.

To finish this job you’re going to wish the right fluid. Most programs use the identical fluid because the brakes: DOT four, 5, or 5.1. However some use straight mineral oil, normally Magura programs. After you have your oil, you simply want a transparent tube, a catch bottle, an 8mm wrench for the bleed nipple, a syringe or one other technique to suck the fluid out of the reservoir, and no matter instruments it could take to take away the quilt or cap on the grasp cylinder reservoir.
Pop the highest on the reservoir, ensuring you lay out rags to guard the paint you probably have any drips. Try the rubber diaphragm. Test it over for any tears, pinholes, or cracks. Give it wipe-down with a paper towel; rags go away fiber and fuzz. Don’t use brake cleaner or contact cleaner on this; these chemical compounds will make the rubber swell or distort and it received’t seal correctly if you set up it.
Subsequent suck nearly all of the oil fluid from the reservoir. Then fill it up with the brand new fluid that you’ll be pushing by means of the system to flush out the outdated. You wish to use a brand new bottle, as hydraulic fluid can take in water over time, whether or not that’s within the system in your bike or within the bottle on the shelf. Recent is finest. As we transfer the outdated fluid down and out by means of the traces, you wish to be sure that the extent of the fluid within the reservoir doesn’t drop so low you suck air. Otherwise you’ll be again to sq. one.
On the slave cylinder, put your 8mm wrench over the nipple and fasten the clear hose. The tube ought to attain the bottle of the catch bottle; I wish to make a gap within the cap to carry the tube and hold it in place. Having some fluid on the backside and overlaying the tube helps to maintain air from touring up and again into the system.
Similar to bleeding your brakes, squeeze the lever after which loosen the nipple simply sufficient for the fluid to come back out. Don’t launch the lever till you shut the nipple. You received’t have the agency after which delicate lever like on a brake system to remind you that you’re pushing fluid by means of the system, so it’s simpler to neglect to maintain the lever in till the bleeder is closed. Repeat the squeeze, crack, shut, and launch till the fluid runs clear. And hold your eye on that fluid stage!
After the fluid is evident, change the reservoir diaphragm and cap. Clear up. Give the lever a number of squeezes, fireplace up the bike, and examine the operation. That’s it!
