Disc Brakes

I'm looking forward to getting the discs on our 5er. I (see above) ended up purchasing a Bludot hard line kit from Eastern Marine. It has 6 'rubber' flex lines, three tees and enough lengths of hard line to easily plumb the unit. The kit did include a couple short lengths with a tight 90* bend that I have no idea how to use for my particular project so bought some additional line from NAPA. I also want to run a flex line from the actuator through the floor to meet the long line to the axles. The interesting part of the project was straightening those 1 foot diameter coiled up lengths. The straightening 'die' was an ~ 24" piece of dimensional lumber with a slot dadoed on my table saw just a slight bit wider then the 3/16" line and about 1/4" deep. I then cut a 6" piece and a 3" piece from that wood chunk. The line was passed through that slot an inch or so at a time using two shorter piece to get things started then the longer one. The three lines which are fairly short turned out virtually dead straight with a little hand tweaking. The long line (20 feet) is just OK but will be 'tweaked' when cut to final length.

Now - when is spring coming to finish my project :-}.

Had to make our first emergency stop this weekend. 70 to 0 in a flash thanks to a traffic accident in front of us. Stopped fast enough that the F-150 apparently tailgating the trailer (couldn't see them, didn't know they were back there) had to swerve off the road to avoid us!

I have the same setup, I would take the caliper off and see if there's some misalignment or possible sticking piston.

Pad looks misaligned in the caliper. Have you removed to inspect?

700 miles on the brakes and they are great. Had to make a hard stop at interstate speeds and it was nice not to panic with the trailer pushing the truck.

one issue is one of the pads is not wearing on the disc properly, waiting to hear from Ron. the back side pad is good as is all the others.

Any ideas?

Pic 1 normal wear.

So as long as you will be bleeding the brakes again might be a good time to get the tool and clean it up ;)

I'm in the process of putting my order together for a disc brake mod on our 5er. I'm at the point of adding a brake line kit and prefer using cut to proper length hard lines (yes, I have good tools for proper 37 degree flares plus tube benders) but have 3 of the MORryde X Factor spring bracket cross members to install at the same time. These cross members are located against the 5ers belly and add a few 'kinks' to the hard line assemblies. This brings up a Kodiak product which is a flexible brake line. My history using lengthy non-reinforced flex lines on high pressure systems is that they lead to spongy and inconsistent component actuation. This brings me to my questions - (1) has anyone used that Kodiak flexible line kit and (2)if so, is there any less then great brake application.

I had issues going from side to side by the axles myself. So, I elected to Tee the lines in the front and run one line down each side. Then I tee'd at the wheel again.

The steel lines can be bent easily by hand without a tool

So just a thought for those with disc, consider a path of protection in your installs. I even considered running the main line inside of a heavy gas line tube down the side to the split to protect from such a thing in the future.

That was my focus, I ran the main line along the inboard edge of the main gas line. Then ran the crossover line against the rear edge of the gas crossover line. The remaining lines are straight and as close as possible to the inboard edge of the trim securing the underbelly fabric. Nothing exposed against the side of the I-beam. Unfortunately not much can be done to protect the flex hoses.

I would strongly advise to re bleed the brakes after the first 100 miles or less.

yes, planning on it :)
