Yes, it's not easy to bring all air out the system when you have AP-master zylinders. The alcons are much more easier.Curves Junkie wrote: ↑Fri Aug 19, 2022 9:28 am @plip1953
Sound good
I am curious about your driving report.
Do you have forgotten to order the bias adjuster?
Please show the partNo. of the valve.

Following yesterday's outing, we at Cadwell Park we were surprised by the degree of effect that the change in rear master cylinder actually had such that having we ended up with the brake bias needing to be set quite a long way to the rears to prevent front lockups. Our ideal is still to be able to run as close as possible to 50:50, but it's not really a problem if it ends up needing to be set somewhere else other than in respect of limiting further adjustment to account for, say, wet weather conditions. For now I think we'll leave is as 0.7" front and 0.8125" rear, but could end upback at 0.7" front, 0.75" rear or even 0.75" front and 0.8125" rear.
The AP lever type proportioning valve wasn't used or needed to be used at point.
The brake master cylinders on the Atom 4 are Tiltons and incorporate their own bleed valves, which is handy, but the clutch master cylinder is an AP.
