Van Diemen 2000 Aim brake pressure mount location?

[redcar9]

I'm trying to measure brake pressure using the aim pressure sensor. However it doesn't clear the front ARB.
Thoughts on how to solve this?

Gets a little tight up there.....

I did the following:

I used a pair of these:

And made a mount like this:

And stacked the hoses on the masters.

The mount is a 3d print with brass 1032 inserts.

okay that's freaking cool!

I made a bracket that clamps onto the rack to mount my brake pressure manifolds.

My personal setup is very close to same as Davids, works great, sensors aim down with bleeders at top, no air pockets.

Best to soft-mount pressure transducers like these, on rubber blocks, with a short hydraulic pigtail "Tee-d" off the brake line fitting. Just be sure to fully bleed the pigtail so air doesn't get into the brake line. Unless you're using a pair of them to determine brake balance, doesn't matter if its in the front or rear line, use what ever's convenient.

If you use AP masters, the reservoir is behind the outlet so there is no clearance issue to the FARB. Then you can use a banjo bolt with a pressure tap built into the head and thread the pressure sensor right into the banjo. A lot less potential leak points this way and the AP masters are really nice parts to work with.

Do you have any pictures of this setup?

I've seen M10 banjo bolts with a tapped head but no 3/8". Where can I find some?

The description says "chrome" but they are actually a satin nickel finish. They look nice. I've used them on dozens of brake pressure setups over the last 15 years. I keep 5-6 of them in stock at all times just for this reason.

This is an old pic with the old style pressure sensors, but you can see the AP masters, the banjo bolts, etc. And FWIW, the newer style AIM pressure sensors fit even better.

Question on the above picture. How do you bleed the air out of the sensors?

I haven't installed them on Rock's car yet but looking at the sensor and the banjo bolt as an assembly I don't think there will be much if any air to bleed. It should be very similar to a standard banjo without a sensor. I'll let Ethan confirm.

When did mine last, I bled the lines first, then filed the sensors with an eyedropper(recommended by TimW), gently tapping to make sure there was no trapped air. Worked great with a firm pedal.

Never had an issue with air in the sensors. I suppose Dan’s suggestion of filling the sensor with a dropper first is a good “belts and suspenders” approach. But to be honest I’ve just put them in, bled the system and gone racing. Never gave it a second thought.
