As I've done for the past 9 years, when I get into a situation like this, I post for all of thee who know more than I to weigh in on.....thanks in advance.

Heading to CO on Sat for a week, some mild off roading involved (will have kids along).

Got some steel brake lines last week, and my trusted dealer mechanic is concerned about them not being attached as robustly as the factory lines. Here's what he says:

"The factory lines have a locating pin on the caliper to prevent from spinning loose when turning wheel and these lines do not have that on them."

And a trusted mechanic I've gotten to know from buying gear from says this:

Many aftermarket brake lines do not have any sort of tabs or pins on them to Locate them on the caliper. There are a couple reasons why they do not, but we find that in some circumstances this can be a good thing. You will sometimes find that with the extended brake lines that you will need to move how the line comes off of the caliper to prevent interference issues with the suspension and the tires. I run brake lines like these on both my personal vehicles and have never had one just come loose, and I wheel both of them pretty hard. I also get under the vehicle from time to time to inspect and tighten all of the bolts.

The place that sold the lines upon reading the dealer's concern said:
"Yes, that is how they are suppose to be. No aftermarket lines have that pin. Go ahead and install them, everything will be fine."


Can anyone weigh in on this? Having a brakeline come unattached is something I obviously want to avoid, but would like the extra feel and durability of the steel lines.

Thanks!

I think the pin is on the oem lines as an assembly aid at the factory, more so than to keep the fitting from moving.

Anecdotally, I've wheeled the poo out of bikes and cars and trucks for a long time...I've never seen a brake line loosen, assuming it was correctly routed during installation...On some fast and bumpy runs (e.g., Barstow to Vegas) I've drilled the bolt head and safety-wired the bolt to the steel pipe adjacent to the banjo.

Use FSM torque values on the banjo bolts. Use new copper washers, or anneal the old ones and reuse...heat to cherry-red on the stove or with a propane torch, and drop the washer immediately into a can of cold water.

No sweat. ;)

Report back on how the installation goes.
