Build Friends,
These pics show what looks like a stubborn brake fluid air bubble in the remote reservoir adapter at the master cylinder tops. The brakes have been bled manually one corner at a time and the pedal is firm. This “bubble” expands/moves when brakes are applied. The reservoir fluid level is above the MCs but the feed hose from reservoir to MC adapter is level with or just below the MC at times as it travels through the footbox front.

Parts:
Tilton 75-750 with remote adapter
FFR fluid reservoirs with 1/8NPT to 5/16 barb fitting
5/16” hose from reservoir to MC adapter
3AN male to 3AN male
3AN Brake fittings/lines

The previous Wilwood MC had black remote adapters so it may have had the same pocket and I wouldn’t know it.

The air pockets have been there a week and I re-bled the corners yesterday and they remain. While the brakes feel good now, it seems during handling forces the bubble could move and get “sucked” into the cylinder.

Is it time for a pressure bleed?
