V1 Brake reservoir relocation

[ManDan1957]

I got the adapter for the master cylinder with the brass 90’s but how do I attach the hoses to the reservoir?

I am not sure what the question really is here. The reservoir also has a machined aluminum piece that it sits into, then it has some brass 90's on it as well, and you hook it all together with some hose. Did you not get the brake reservoir remote mount maybe? I know at one point DF was waiting for a batch of them from the machine shop.

Sounds like I’m missing the reservoir parts. That would make sense. Thanks

Bump for a silly question... is it common to have the master cylinder fitting to get shavings while threading the new brass fittings into it?

 

[Ross]

Well it is common for the threads to not be perfect, and have some resistance or friction when inserting.
Just clean up the shaving. I would take it apart, put some kind of thread sealant or thread lock in there, otherwise you may have a leak.

Might be a stupid question, but why do we relocate the master cylinder fluid reservoir? Is there a clearance issue?

 

[Rttoys]

Yes. The hood will not clear the master reservoir.

What did people use for the lines from the res to master?

They are supplied by DF. It’s some of that black plastic hard line. There should be adaptors for the res and master too. Some people upgrade to braided flex line.

Taken from Jeff's thread, I also went this route.

As with many others, I didn't like the hoses on the master brake cylinder going to the reservoir, so I had to upgrade... well I didn't have to... you all know how it goes.

Sure, I ordered them from Summit Racing. The part numbers are as follows:

VPE-10251A from Vibrant
Fitting, Adapter, 90 Degree, Male -4 AN to Male 1/8 in. NPT, Aluminum, Black Anodized, Each
(Mfr. #: 10251A)

VPE-11351 from Vibrant
-4AN to 1/8"NPT Male Swivel 90 Degree Adapter Fitting
(Mfr. #: 11351)

RUS-659020 from Russell
Brake Line, Competition, Braided Stainless Steel, 18 in. Length, -4 AN Female, -4 AN Female, Each
(Mfr. #: 659020)

At first I thought the 18 inches lines were going to be too short, but they are perfect. The fittings on the reservoir will swivel, but you don't have to go that way if you can get the non-swivel pointed in the right direction.

I assume everybody has the reservoir installed the same way, but I’ll ask my question anyway. Is it a problem that the reservoir hoses go upward towards the master cylinder?

 

[Rttoys]

Technically, everything should go always downward, but as long as the highest point (reservoir) is full, fluid will always be in the rest of the system. An air bubble can get trapped at the crest of the line, but a trick to that is to release and hold the reservoir up higher to straighten out the lines, which will move any air upward and out the top.

THIS!! exactly what i did when I found that my clutch line naturally bent upward. ( before the footwell cover was added)

Do you use teflon tape on the brass fittings?

 

[MJP61]

I did not

 

[Rttoys]

There should be no sealers of any sort on brakes. Everything is brass washers, npt or flare sealed.

 

[Lonny]

I use red Loctite to seal the brass elbows where they screw into the aluminum fittings.

 

[k.rollin]

I used the Permatex high temp thread sealant at the locations with NPT threads, and used adapters to convert to -4AN for the run from the remote reservoir to the master cylinder.

Permatex® High Temperature Thread Sealant

OEM specified. Locks and seals threaded fittings. Resists leakage, vibration loosening, moisture, hydraulic fluids and diesel fuels. Lubricates threads for easy assembly and disassembly. Wont shred or wear like Teflon® tape. Parts may be repositioned up to 4 hours after application. Temperature...

Permatex Pneumatic/Hydraulic sealant US Part Number: 54540 . Amazon lists it at around 24$. I have that and used it on my Stalker brake fittings.
Unfortunately, it is a big bottle and probably enough to do a fleet o Goblins.
