Banjo Bolt 2000 Cobra R Brembos

[CJHAMIL]

I am overhauling my brake setup with new rotors, lines, pads, and I am painting the Brembos. I am considering buying new hardware for everything just to have it done while I am at it. One thing I came across is when you switch to stainless lines you have to get a different banjo bolt. Is this true and if it is can someone provide a good part number for the correct bolt? I've done some searching and I have not found anything definitive.

Unless your current banjo bolt is damaged somehow it's ok to reuse. You do need to replace the copper washers though.

I haven't heard of needing different bolts because of the lines themselves. Usually it's the calipers that need a different bolt because of thread pitch.

Did some more digging apparently only the MM stainless line kit requires a different banjo bolt. MM sells the bolt but it does not come in the line kit.

Interesting. I wonder why they're set up has a different bolt? I remember the line kit I bought came with bolts, but I didn't use them as I was swapping to the Baer set up and they had their own bolts.

I wonder if the block is shorter on the MM kit to where you need a shorter banjo bolt.

I am willing to bet its by no means a special bolt and you can probably find a set at your local parts store.

You just need one with good thread engagement that lines up with the slot cut into the line end.

There are two reasons you might need a new banjo bolt. First, the existing one may be either too long or too short. Too short and it might strip out when tightened (or come loose). Too long and it'll bottom in the hole before it seals the fitting.

The second reason is more esoteric. Banjo fittings come in two basic types. If you look into the hole in the hose-end fitting that the banjo bolt goes through, you might see a channel and you might not. Some fittings have a channel milled in the wall of the bolt hole to allow fluid to flow around the bolt and go through the hole on the side of the bolt and into the caliper. These fittings will work fine with any banjo bolt - straight sided or with a machined groove.

Other fittings come with a straight sided hole (think "drilled") and require a groove cut around the banjo bolt so fluid can flow around the bolt and into the hole. These fittings will only work with grooved bolts. If you use a straight-sided bolt, brake fluid is blocked and you have no brakes.

So, that's how you can tell if you need new bolts. What your car came with and what the new lines come with, I have no idea, but hopefully you can figure it out from here.

So I know the point of banjo bolts and how to tell if I need a new one. I was mainly curious if what I had read was actually true in regards to if you have stainless lines then you have to get a different dimension bolt. Upon more research I found this is only true for the MM kit. Since I have the Russel stainless line kit coming in I just ordered OEM banjo bolts (front and rear), caliper hardware (front and rear), and everything in between. Only grey area I am in is if the OEM banjo bolt is different than the one that came with the 2000 Cobra R calipers. I'll cross that bridge when I get there.

Sounds good. It'll be interesting to hear what you find when you get yours apart.

The earliest Ford I've done brake lines on is a 2011, so I'm not familiar with the earlier cars. All the Ford OEM Brembo calipers I've worked on (2011, 2014 and 2016 Mustangs) have all taken an M10x1.5 bolt. Every aftermarket caliper in the world takes M10x1.0. Mind the length too - the Ford OEM hoses I've encountered use an extra-thick banjo fitting and most aftermarket stainless lines use a thinner one.

Got everything wrapped up last week and I have had time to verify everything is good to go. Encountered an "oh S**T moment" when the banjo bolt in both front calipers stripped when I tried to torque them. Before I broke out the credit card again to buy the 14" 6 piston Brembo kit I figured I'd give it another try. I cleaned the destroyed threads out and found I had 7-8 good threads in both calipers. Went to Advanced Auto and got fine thread M10x1.0 GM HD truck banjo bolts. They fit and they torqued to spec so crisis averted. Of note 94-02 Mustangs (to include all trims even 00R) have fine thread banjo bolts and the 03-04 have course thread.

I'll get some pics up before too long but everything is new other than the calipers front and rear. StopTech Cryo rotors, Russell stainless lines, Hawk HPS pads, and new hardware from LMR (every nut bolt and washer). The banjo bolts provided by LMR are great and they do not leak.
