Honda Varadero Brake Clean

Well, I had a look at the front brake pads on my Varadero the other week. so I loosened up all the nuts while it was on the bike (to get better leverage on things like the pad retaining pins), wiggled the caliper to push the caliper pistons back into the caliper body and took the calipers off the bike.

The pads have plenty of friction material left, so I decided not to change them yet. I did get an old toothbrush and some brake cleaner, push the pistons out a bit and clean off some of the crud that had built up. so the pistons and caliper body were a bit cleaner. I then put it all back together.

While the friction material on the pads was fine, I did notice that the back of the pads had a really bad build up of muck on the back of them, but I had a good look and it didn't look like it would affect braking at all, so I just put them back into the calipers.

Of course, next day, on my way to work, I'm pootling along the motorway and all of a sudden the brakes start to drag. I pulled the clutch in, and yep it's definitely the brakes. They just came on suddenly and started dragging.

Okay, my normal fix for this (whilst on the motorway) is to pull into lane one, make sure that no one is behind me and to apply the brakes hard. I believe that this will help the caliper pistons get pushed back into the caliper body. So I pull in to lane one, but there is a car behind me.

Well, as I'm now beginning to slow, I hoped that the car would overtake me soon. but he didn't, so I couldn't apply the brakes.

As I was working out what to do next, the brakes freed themselves.

Okay, at least I can continue on to work.

on the way, I was thinking that it was a bit of a coincidence that I had played with the brakes the day before. So I started thinking about it a bit, and guessed that some of the crud that had built up on the back of the brake pads had come loose and jammed somewhere applying the brakes. Now as the varadero has linked brakes that meant that as the front brakes were applied, the back brake got applied as well.

And I also guessed that the piece of crud either got worked loose due to vibration, or just broke up and the brakes loosened.

So the moral of the story is : If you see crud near your braking system, dont just ignore it. clean it up and make sure that all of the components can move freely.

I have now taken the calipers apart again and used wet and dry on the pads to clean all of the gunk off them, so this shouldn't happen again.

Triathlon Training in the new year

So, my 2019 training has got off to a good start. I'm running regularly and my knees seem to be holding up. I've got a training plan to get me to a middle distance triathlon in September and I am managing the run distances I have set myself. I need to find some longer cycling routes to work and ones with a few hills too, but that shouldn't be a problem. my weekly cycling distance is okay, I just need to move to get my ebike to be doing less of the work. last week I did use my normal commuter bicycle and managed the whole four days as well as my runs, so that was a really good sign. Swimming won't be an issue, I have always found that to be the easy part of a triathlon (not that I'm fast, but I can keep going, and I did manage to swim the distance within the cut off time when I tried the ironman 70.3 last time) The main worry about going longer is my knees. I've got a 10K booked in late January which will test my knees out and I'm hoping that they hold ...

Creating a Watch Face for Android Wear OS 2

Step 1 - Setup my watch for development I have wanted to create a watch face for android wear for a while, but as no new watches were being released my old Moto 360 watch running wear os 1.0 got out of date and I stopped using it. For Christmas 2018 I got a new wear os watch running wear os 2.2 (android os 8.0.0). it has a round 400 x 400 screen and I decided to finally get round to creating myself a custom watch face for it. The first thing I do with all my android devices is to enable developer options. if you don't know how to do that then you can find the method using a google search. I won't give it hear as it opens up all sorts of options that could make android become slow/unusable. Once I had developer options enabled, I turned on USB debugging. This watch (as opposed to my old Moto 360) has a USB connection to the computer, so I don't have to use WiFi debugging (which has to be set up for each debugging session). now on to the watch face creation. St...

Windows Subsystem for Linux Internals

Background Windows Subsystem for Linux was developed by Microsoft to enable command line programs compiled for the Linux operating system to be executed on Windows. To explain the architecture I would like to show the evolution of OS design and how that has enabled this subsystem to be built. Dark Ages (or Back in the Day) Microsoft's MS-DOS was quite primitive in its design (compared to today's OS's). It is a single user OS that can execute one process at a time. DOS had an application programming interface to allow user programs to access some hardware in a device independent way, but only for character-based applications. This allowed applications to display graphical elements emulated with text characters as these screenshots of Microsoft word for DOS show: This is Microsoft Word version 1. To use these programs you had to remember key combinations to bring up the menus and used the cursor keys to navigate around the screen. If the a...
