Just bought shimano saint 09 disc brake, found out that the cable is too long, plan to reduce the length. Someone recommended this way, remove the cable from the caliper, then cut the cable, install new olive and install back the cable, this way no bleeding require. Is this way work?

is a new set, already bleeded, ready to use, just cable too long. Idea given was, just cut the cable, and replace with new olive and install back. When the caliper and reservoir never open, the oil won't drop out. Just want to know about this method of reducing the cable.

What he was saying is that hydraulic's don't use a CABLE. They use fluid.

If you disconnect the hydraulic line, you will introduce air into the system, and have to bleed the brakes.

You will need a new olive AND an insert to shorten the hose. Then you will have to bleed the brakes. No way around it.

sorry sorry, i used the wrong word, the set already ready to use, just the cable too long, so i was recommended to use this method to reduce the length of the hose, which is remove the hose from caliper side, then sut, then put the new olive and install it back. NOT CABLE is disc brake hose. WIth out removing the reservoir cap and caliper nut. Is this work? hope u guys understand wht i mean here, thanks

What you are saying works sometimes, but most of the time not.

If you want to try that here is how to do it.

First always when working on your brakes, remove the brake pads and put the aside where they will not have any chance of being contaminated with brake fluid.

Pump the lever a few times (to push the pistons out some) before you cut the hose. Then remove the hose from the lever end. Then cut the hose, install new olive and insert and then re-attach the hose. Then force the pistons back in and hopefully any air introduced will be pushed out and no bleed will be required.

If you did it exactly right, it will feel good. Chances are there will still be some air and it won't feel quite right. It's best to bleed. Shimano brakes are super easy to bleed, no bleed kit required just a rubber hose and bottle to catch the fluid in. You bleed Shimano brakes exactly like you bleed car brakes.
