I am about to order a pair of banjo bolts for the Mustang PBR front calipers.

M2320-F Bullitt Calipers


For cost savings, I wanted to get the PBR Cobra calipers but they were sold out
or are no longer available. The Wilwoods are out of my price range at this time.
So... To make a long story short, I ended up with the calipers for the Bullitt.

For those who have or know of a friend who's done this before, I just need
a confirmation from you that I am ordering the correct part ASAP. I have
searched and am getting conflicting data from different sources. As far as
I understand, the correct part to order is;



Hydraulic Brake Fitting (Banjo) Bolt - M10 x 1.0 x 26.5mm (Fine pitch thread)


Ford part# W706548

or

General Motors # 10286122




Is this correct?


Also, Does anyone know if the crush washers come with the bolts?
My local O'Reillys may have some in stock but I do not know
the size I am suppose to get.

I think Laser needs to jump in here as he went through this with the White Mark as well. Maybe even check his progress thread it might be there.
 
The people you order from should be able to tell you the thread pitch if not
just order both and return the one's you don't need
 
Is the use of teflon tape sealer or blue thread locker recommended on
the banjo bolt to keep any fluid leaks from happening ?


Or would you just rely on the crush washers as your main and only seal?


This caliper upgrade is probably going to be a one-time deal for me. If I ever need
to replace the caliper with something bigger, it will be years till that might happen.

Do not use any thread locker or the like on the banjo bolt for several reasons
1) it could contaminate the brake fluid which would ruin the caliper and hose, and abs, and master cylinder.
2) the hose and caliper won't last forever, you'll want to be able to take it apart again (about 50k miles is suggested for a caliper rebuild)
3) thread locker could cause a blockage in the bolt, which results in a difference in pressure
You can take the caliper and hose with you to the Ford house and make sure they're giving you the correct bolt, just do a mock assembly on the table with the washers to ensure proper length

And it won't be a GM part # because it's a FORD product
 
I will be flushing my brake fluid in a few weeks. Still waiting on some
parts to arrive. In the mean time, I am looking into upgrading my choice
of brake fluid.

Keeping in mind that I drive in an area of the country where some
interstate roads have steep downgrades as much as 5%-6% and
sometimes steeper at some Appalachian mountain sides. And I am
concerned about the laws of thermal dynamics on my brakes system
when stressed especially during mid-summer days when it is extremely hot.

The fluids used on our cars are Glycol based (DOT3 and DOT4) and are
not compatible with Silicone based (DOT5 and DOT5.1) brake fluids. So
that means I have to stick with DOT3 or 4 brake fluids. DOT3 and 4
are interchangable without introducing any problems to the system.

There is also a minimum boiling point classified by the Dept.of
Transportation as Dry and Wet. Minimum Dry boiling point is established at
401*F and the Wet boiling point at 284*F. I do not know how long ago
the brake fluid was replaced in my '97. It's been there since I purchased it.
I have since logged over 1000 miles since. The Dry spec for this car
has since been obsolete and the Wet BP may have fallen below
minimum specs.


I am looking into using a product with a higher than than minimum Wet
boiling point of 392*F. There are other compatible brake fluids having a
min. BP of 518*F but those are uber-exotic stuff racing teams use so we
wont get into that. My wife would kill me if she knew I spent $70. on
just one liter of this stuff.


The Brake fluid I am putting in my car is the
ATe Super Blue Racing DOT4 .

It costs a little more than your typical Brake fluid, but with its properties,
it can stay in the car a little longer. It is easier on the budget too. It is
about $16. per liter, USD.


I should benefit from this upgrade on @X track days.
Does anyone have any experience with this type or brand fluid in their daily driver?

Sorry I missed this thread earlier. In my White progress thread I list the bolt size needed. Also get OEM Ford washers, not the parts store ones. The Ford ones are thicker and keep the banjo bolt from striking the caliper. You will also need to move the pistons out a hair before installation or the bolt will hit them.

I also used that same brake fluid and really liked it. Never had brake fade or a mushy pedal. I also installed the braided lines they sell on ebay for $150.

Gen 1&2 have the same banjo bolt as does the 03/04 Cobra calipers. The Bullit and some early Machs have a different banjo bolt. They also have slightly smaller caliper pistons.

Ah so my Mach calipers just happen to have the matching threads.Cool.
