I posted a thread a couple of weeks ago about my trials and tribulations of replacing a tube, as it took me 4 attempts and 4 tubes. It was thanks to the folks on here that I got my success in the end.

Out riding over Xmas I was having trouble with gears slipping and the rear disc brake hardly working. All expected as the bike was new 5 weeks ago and cables stretched and need tweaking, a few bits tightened etc. Struggling for time to get to the place of purchase for my free fix, so got in touch with a mobile service/repair guy. Yes I appreciate that there will be many on here who throw up in disgust because I'm no 'techie' and can afford to have someone do running repairs and servicing.

The guy arrived as planned and spent ages sorting my steed out, and I was really impressed with his thoroughness, as even the spokes were tightened, every nut was checked, a hub was too tight? so sorted full lube etc, etc, etc. Great bloke who really knows his stuff, and chatting with him afterwards (Even a bike-fit done) he said that my disc pads are contaminated, especially the rear. he then told me how I had done it, because it was my fault. It does make sense though, as I had sprayed some lube onto the cassette and the breeze will have blown some over onto the disc and hey presto ..... The disc brake stops working and then starts working a bit, but whatever you try and do the brake will never work properly again. The front pad works pretty well but not as it should because i had wiped the disc with a cloth that will have been contaminated with lube or cleaning stuff.

So new pads required because I don't know any different. So be warned if you have disc brakes, make sure you keep lube away from the rear wheel. he laughed and asked me why i didn't think to use the lube on the front and use the pedals to spin the chain and lube the rear by changing gear. Yes I'm an idiot but I keep picking up really good tips :blush:

Easy mistake to make. I never use spray lubes as it always goes everywhere but where you want it. I also never lube the cassette directly, I just lube the chain, that's all you need.

You should be well sorted now though and you have found a good mechanic to call on in emergencies :thumbsup:

You are not an idiot.:thumbsdown: You are new to bikes and there is a learning curve.
Unfortunately we often learn by our mistakes. The up side to this is that such lessons are not forgotten and stand you in good stead for the future.
Carry on and you will soon be as good as your mobile mechanic.:thumbsup:^_^
Happy biking.

I know I'll get slaughtered here but I get quite liberal with the GT85 after a wet ride on my mtb to save the hassle of cleaning straight away and get it on the discs etc. I've always found if you can get some heat into the brakes you'll burn small amounts of contaminants off quite quickly after and your back to normal! Depends where you ride and how confident you are initially I guess as it takes speed to generate the heat initially.

GT85 is ok to spray because it evaporates ... I think :smile:
@Doc333 don't be so hard on yourself, how are you supposed to learn if not by experience?
On one of our rides a girl had stuck disk brakes, so she proceeded to douse them with water.
Another rider said: should you not be spraying them with oil or something? :eek:
She knows better now, potential catastrophe avoided.

Agreed, and admitting you made a mistake makes you even smarter. I've made a few mistakes while working on bicycles that make me cringe to recall :blush:.

I was 16 and had my first motorcycle. It suddenly puttered to a halt one day so I dismounted and stood beside it with my hands on my hips looking at the engine: this was the extent of my mechanical knowledge. A few minutes later a guy on a bigger motorcycle stopped and asked if I needed help, I guess the hands on hips indicated this. He took out a tool kit and removed the spark plug, he blew on it and put it back crossing the thread and heaving on it, now Doc this is a fuing idiot.
You may have guessed that I was out of gas.
