Also the MC linkage should be adjusted as per the manual. | | | | | Joined: Aug 2011 Posts: 36 'Bolter | | 'Bolter Joined: Aug 2011 Posts: 36 | I'll try taking some fuild out,still confused on reason for a hole in the top of the cap.Wouldn't it let air in? | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | yes it lets air in, to allow fluid movement in and out of the MC - the level should be slightly below what the inside of the cap would touch, not filled to the rim - also, you may find the system hasn't had the air fully bled out and that air is pushing back against the fluid in the MC .... the exposure to ambient air is the drawback of the old simple systems, the fluid will slowly absorb moisture, so should be flushed and changed occasionally

What should I use to do the flush? Do I just run brake fluid through the lines, or is there a brake system cleaner? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | You can flush them with alcohol but time you bleed them you will get all the old fluid out.
