Dragging back brake

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.

Dragging back brake

Postby Mikey » Mon Apr 30, 2018 8:59 pm

How is it best to lubricate back brake foot lever? Parking brake activates fine. But I have to pull up the foot pedal by hand or it holds the brakes on.

Happened suddenly mid ride.

I usually have to disassemble it, clean it up and re-lube the shaft. I think Tomcatfixer put a grease fitting on his.

Every couple of years I have to remove the brake pedal and lube the shaft it pivots on. This year I'm actually going to install a zirk fitting so I can grease it that way, as it will be much easier to do.
The shaft isn't sealed and gets lots of crud on it which makes the brake pedal bind.

Ok, got it off and yah. Just....yah.

So I'm going to sand it and lube. What's best to lube it? And is retrofitting a zerk as easy as drilling and tapping thread? Or so you need channels? Or will the grease just wick it's way around?

Some have drilled and tapped the shaft. I was thinking of putting a 10-32 zerk in the tube. If I do install a zerk, I will probably grind a shallow spiral channel on the shaft too. Since procrastination is my favorite occupation, I will probably wait until it drags again.

As said pivot shaft seizes up. Occasional bit of oil dribbled into each end or I’ve also got an aerosol grease.

Tomcatfixer installed a zerk fitting. Do a search, should be easy to find.

Don't forget to grease? Yah, it's on there quite loosely I found. Worth lubricating. I can't believe it started to seize within 2k kms

The pedal on my 07 patrol started dragging rather early too, but rather than adding a zerk, I just give it a little oil on a fairly regular basis, and it's been fine since. lubing it with oil was on my short list of things to do when I brought home my M70.
A zerk is probably Ideal as it's neater, but it's not a necessity, if one makes it part of their regular maintenence.

I think Van was the originator of the grease fitting adaptation. If I remember correctly his first attempt was to put one on the outer tube and then later he used the shaft itself. I filled mine up marine grease and just apply oil to the exposed ends regularly. I havent had to break the pedal down for a couple of years. That said I admit to being a bit of a "fair weather " rider mostly due to arthritis, artificial joints and a growing case of DAS (discomfort avoidance syndrome).
