Project Z750 part 12

Okay, I've been to halfords and bought a small bottle of brake fluid, so now I can get the pistons out of the front caliper, and start cleaning them up. first thing is to fill up the fluid resevoir and bleed the new fluid through. as the front has two calipers, bleeding the new fluid through is being a pan, so i had a brainwave! attach the front caliper to the rear system, as that is a lot less brake hose and no second caliper to make things harder.

of course bleeding the brakes with the caliper off the bike is not something i would recommend. I had one hand holding the caliper still so that i could turn the spanner on the bleed nipple. my other hand was on the spanner to loosen and tighten the bleed nipple, which left my foot to press on the the brake pedal whilst trying to synchronise all three limbs.

okay, this isn't working, so I've ordered a brake bleed helper (which will make the final refit easier) and i'll try again when that arrives.

while I'm waiting, I take the pistons out of the free caliper and start polishing them. with the autosol i found, they are cleaning up a treat. there is some really stubborn crud on the rear and i suspect i'll get some on the front as well. sure enough a lot of the crud comes off easily, but i am really going to have to work to get the pistons completely clean.

What does "Full Stack" mean?

I've been a software engineer for a little while and I see the term "Full Stack developer" more and more, but what does it mean? Okay, let's walk through what a complete system will comprise of and see if we can work it out. UI First (from the users perspective) is the UI. It's how they interact and really all they care about (as long as the application does what is expected of it. Here is a list of some UI technologies that I know of AWT Swing Qt Android XML MFC and VB OpenGl Vulkan Communication Protocol Next up is the communications protocol (as most applications these days are a thin UI talking to a backend server (we've gone back to the mainframe era!) RPC FTP SNMP SMTP DDS ActiveMq/RabbitMq Network Layer The communications protocol has to be transported between the client and the server somehow, so here we have the network layer IPX/SPX Token Ring Bluetooth USB Server So now we have data being transferred between t...

Project Z750 part 36 - the finalle

I took the bike for a quick test ride round the block and it was fine. it actually cornered now that I had sorted out the tyre pressures. and the brakes all work. I gave the bike a quick look over and noticed that I hadn't marked the rear caliper bolts. (I mark each bolt when I tighten it up to the specified torque so that I can see if it loosens up. so if you look at my bikes you'll see white dots on a lot of the bolts.). As I hadn't marked it, I hadn't tightened it up fully, so I torqued it up and marked it. The bike shop I use managed to fit my in for an MOT before they went off to the Isle of Man Classic TT, so that morning, I got my gear on, wheeled the bike out of the garage, said a quick prayer (I'm not religious, but it can't hurt), and I then put my life in my own hands. I mean that even though I ride every day, I had never before done this much work on a bike. I'd changed braked pads, but never replaced the brake seals, and although I had tor...

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 ...
