Forte Triple Reservoir installation - your opinion

[TXJosh]

Howdy all
Just finished installing my forte triple reservoir and am curious

1. if the reservoirs at top of caps is too high relative to the 3/4” chassis rail risking hood interference. Do I have any clearance there at all?
2. If these are insufficiently level.
3. Height relative to master cylinders. My intention is to route the hoses through the old clutch cable hole on the driver side of the divers front foot box wall. This results in a barely if at all net downward slope from reservoir fitting to clutch cable hole. How have other dealt with it?


Thank you for your advice… I’ve seen many posts on this topic before but am now into the nuance and have my own pics to share so appreciate your taking a look.

Mk4 obviously. You should be OK at that height. The clutch hole is a common place to route the hoses to the MC's. As long as it's not excessive, having the hoses go down and back up to the MC's is fine. What matters is the height of the fluid in the reservoirs as compared to the height of the inlets on the MC's.

Yes a MKIV. Sorry for not mentioning that.
Interesting point on reservoir height versus mc.

Thank you

Paul, an you elaborate on this ? Should the fluid level in the reservoirs be higher than inlets on the MC's ?

I can't cite with any calculations or science other than gravity. I'll leave that for others. Us business majors weren't in those classes. :p The fluid pressure in the reservoir due to gravity needs to be enough to push the fluid to the MC's to keep the calipers full as the disk pads wear and the pistons move out to compensate. If the fluid has to go uphill there may not be enough pressure and likely won't work reliably. Basically, I always put the reservoirs as high as I can and I've never had a problem. With the caps at the frame rail as the OP shows it will work. I've done similar with a Mk4 although slightly higher would still clear. What I've observed in my experience is what I stated. As long as the reservoir fluid level is higher than the MC inlet brake fluid flows OK. I helped another builder some time back that had the reservoirs at roughly the same level as the MC's plus long and low loops going through the footbox front. We tried to bench bleed and the setup didn't flow brake fluid to the MC's. Raised the reservoirs and shortened the hoses and all worked OK. I don't know how much that helped. But there you go.

Think of it this way...remember those beer bongs from the ole college days? No one was holding the funnel below their head...

I have the same triple setup. I think you have 2 very easy alternatives. 1) Raise the reservoirs in the clamp so that the clamp is closer to the base. 2) Flip your 90deg mounting bracket and install it on the top of the rail rather than the bottom. Either of those will gain you several inches which should be more than enough. Looks good.

I had always heard there was xomesuction from the MC, and as long as you are not way below, it would take care of itself.

Perfect analogy Greg!!!

Well , when you put it that way, it makes perfect sense ! Lol

Thanks Paul ! I just recently found out a HS friend lives in your area. He's got a Viper ACR, had a Hemi Cuda and just completed a really crazy resto mod Jaguar E type.

But then it may interfere w the hood.
