RE: HELP Bleeding brake
Here is the procedure:
Manual Bleeding:
[ol][*]If vehicle is equipped with power brakes, remove vacuum reserve by applying brakes several times with engine off.[*]Fill master cylinder reservoirs with suitable brake fluid. Be sure to always keep master cylinder reservoirs at least half full during entire bleeding procedure.[*]If master cylinder is suspected to have air in the bore, it must be bled first, as follows:
[ol][*]Disconnect forward brake pipe connection at master cylinder.[*]Allow brake fluid to fill master cylinder bore until it begins to flow from forward pipe connector port.[*]Connect and tighten forward brake pipe at master cylinder.[*]Depress brake pedal slowly one time and hold, then loosen forward brake pipe connection at master cylinder to purge air from bore. Tighten connection, then release brake pedal slowly. Wait 15 seconds, then repeat sequence, including 15 secon wait until all air is purged from bore.[*]Bleed rear bore of master cylinder as front bore was bled.[/ol][*]Bleed right rear brake as follows.
[ol][*]Depress brake pedal slowly on time and hold.[*]Loosen bleeder valve to purge air from brake, then tighten bleeder valve and slowly release pedal.[*]Wait 15 seconds, then repeat the sequence, including 15 second wait, until all air is purged.[/ol][*]Bleed left rear, right front, and left front brakes, in that order, using same method as for right rear brake.[*]Check brake operation and ensure pedal is firm. Also check master cylinder fluid level and add fluid as necessary.[*]Turn off brake warning light by applying moderate pressure to the brake pedal several times.[*]Road test vehicle[/ol]
