Good Morning,
This past winter I replaced the front brake pads and flushed the front brake system with Motul RF600 DOT 4 fluid. All was well.

After about 200 miles the front brake was getting soft despite the lever adjustment at 1. I bleed the front brakes again and all was well.

Now after another 200 miles they are getting soft again. I will bleed them again.

I see no leakage and the fluid level is at the normal level.

Do you think the master cylinder needs rebuilding? Is there a kit.

I appreciate any suggestions.

Thanks

KRR

PS I have a 2004, completely stock and would like to keep it stock.

I want to end the story. I checked the calipers, they were dry. I purchased a rebuild kit for the master cylinder ($35) and the brakes have been fine for the past two weeks. Found dirt and the main piston seal in the master cylinder looked worn.

Thank you

KRR
