front brake issue.

[Im Faster]

It took me a long time.. but i bled the mc over and over and over.. then everything else.. then the mc again and again.. and it finally worked..

Not sure if it was mentioned but make sure you grease the pins lightlty on the calipers while you have eveything apart

do i need to just replace the calipers?

Sorry to hear you dropped the bike. That sucks big time.

Did you ever tear down the master cylinder? The only way to properly clean it is to tear it down all the way, scrub it out with soap and water, and then inspect the parts and replace parts as necessary. The rubber brake lines should go in the trash; they are sure to be soft and contaminated on the inside with scale.

Please do the job right before you really get hurt.

Thoroughly clean out the master cylinder and brake caliper(s) with Brake Cleaner
and lubricate the internal parts with clean Brake Fluid.
Not a bad idea at all to replace the front brake lines at this time either.

Well the return port was for sure clogged.. now when i pump the brakes i get some brakefluid that shoots 6-8 inched up out of the master cylinder..

HOWEVER..

after bleeding the brakes a few times..

they still feel soft.. compared to before..

maybe they are how they should be.. but i feel they could stop me sooner.. at least they use to stop me much faster.. and i can pull the lever all the way in.

The lever coming all the way in could be caused by the rubber lines expanding like a balloon. There is a reason Suzuki says to replace them every two years.

It could also be air, or a problem in the calipers or the MC itself...
If the brakes are not stopping you as well as they were you still have a problem.

They do look like thy have been replaced recently.. but i cant be fore sure..

should i try to bleed more? or what..

[Nessism]

Maybe I'm slow, did you tear down the master cylinder or not?

My suggestion is to replace the brake lines and ditch the anti-dive, which doesn't do much other than make the brakes feel spongy.

yea today i took it apart again and cleaned it again.. the right way..
