Project Z750 part 13

Just a quick picture of what it should look like to remind me !!

Between piston polishing I've been trying to get the sliders off the calipers, but they are stuck fast. I really can't see how to get these sliders out. I've been through the Haynes manual and it says the sliders should just slide off, there are no bolts or screws keeping it attached, but they won't budge.

Having now looked at the "Rebuild Kit Full Seals Caliper", one of the caliper slider pins has a rubber boot that goes through the hole and comes out the other side with the slider pin inside it. Seeing as I will be replacing all of the rubber bits on the calipers, I cut the end of the boot off so that I could get to the other side of the pin to see if I could push it through, but still no luck. still it did allow me to spray WD40 on the other side of the pin (I'd already sprayed some into the boot to try and free it).

so I carry on polishing the brake pistons while I think through how to get these sliders off.

looking at the rubber boot that the pin goes through, I thought that if I pull on the exposed bit of boot, it might help pull the slider pin out, so I cut the boot part of it, grabbed it with pliers and pulled.

I theorised that pulling on the boot would make the rubber inside around the slider pin thinner and lo and behold, the slider popped off (literally popped off and ended up on the floor). finally something going well. so that's the rear caliper completely dismantled.

So I try the same trick on one of the front caliper sliders and to my amazement, it worked (I really thought my luck would run out), so now the other front caliper. I tried to get a good purchase on the rubber boot with my locking pliers. once they were attached to the rubber, I pulled gently, but the pliers slipped off. whoops, okay a bit more pressure with the pliers and try again. so I start pulling and the rubber is stretching, looks like its going to work.

but of course it didn't work. something had to go wrong, and in this case, the rubber split around the pin and left me with almost no rubber showing, so no more rubber to grip to try my pulling technique.

okay, what now? well, my wife suggested that I try heat to free the pin, so I have now ordered some gas for my little hand held butane torch, and when that arrives, we'll see what we can do.

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

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

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
