2014 Rear Disc Brake Modification

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Your CT shouldn't be too hard to convert. You shouldn't have to make the disc adapter.

Howdy Darrell,

Out Pucking Standing. :clap: :clap: :clap:

This is the way the darn rig should come from the factory, the need to meet dot specs is the reason for the rear caliper with the parking brake. The factory could use this setup and then install a very small caliper just as a parking brake or make it real simple and just put a thing to hold the brake pedal down like they did on the old drum brake. I have been whining to IMWA for the last 5 years, yes 5 because I have been involved with the disk brakes before they became a production item to make it SIMPLE rather then the botched job that it is.

If you make a kit, "I" would be interested in buying one or at least the rotor holder that fits the rear two wheel drive wheel, I can get the rest of the stuff locally.

Any chance of IMWA implementing this configuration, Dave?

Just FYI, not allowed to have something hold down pedal as a parking brake on a hydraulic system, fluid cannot be relied on not to spring a leak. At least I think that's the reason. I agree needs a separate parking calliper then would be much simpler.

As soon as my warranty is over I plan on doing this brake swap. But I will modify a bicycle mechanical disk brake caliper for a parking brake similar to this one:

Darrell-
You said that you thought the cost was worth the effort to change the rear brake on EFI models.

What was the cost breakdown for adapter,3-part caliper mount stuff, caliper and brake line? Even if just standard Ural OE costs for Solo parts, is of interest. Curious.

YMMV

While I didn't keep the receipt for the parts, this is roughly the cost:

IMZ-8.125-27006 Caliper - $120
IMZ-8.123-27015 Brake Line - $30
IMZ-8.1040-20094 Brake Rotor - $150
IMZ-8.123-27055 Caliper Mount Bracket - $50
IMZ-8.123-27052 Linkage Arm - $50

These are only estimates, best to get pricing from your dealer of choice.

Howdy Chad,

As per dot rules, ANY factory build vehicle sold in the USA that has three or more wheels MUST HAVE A PARKING BRAKE. So unless Ural comes up with a different parking brake system I am afraid we are stuck with the crappy setup now in use for a rear brake.

Curious:
Is the Solo 5-hole center plate and the EFI 4-hole center plate the same diameter for the holes? If so, why not just drill 3 other new holes to make a 4 hole pattern to fit the EFI rear? Or if the diameter is different, just drill 4 new holes in the existing new Solo plate? The 5mm thickness would remain the same and no more work required?

That was researched by me and it won't work. There are two problems.

1. One of the four holes falls partially on one of the five holes.
2. On the NG five hole center plate, they have half-circle indentations directly below each of the ears used to attach the rotor. At least one of the four holes falls too close to one of these half-circle indentations.
