Your tech and riding issues sorted
I am a competent home mechanic and have bought a replacement brake line kit for my Ducati Multistrada 1200. Is there anything specific to my bike that I need to be aware of before I set about it with the spanners and bleed kit? John Smith, email
AAnswered by Simon Lane, Hel Performance As well as up to nine brake lines, modern Anti-lock Brake systems feature an ABS control unit with lots of valves and passageways and a separate ECU on a CAN bus system to run the software. Ducatis are generally easier to set up because the design of the ABS control unit seems to allow the fluid to flow through. However, other makes, like Harleys and BMWS run software that opens up all those valves in such a way that it is very easy to get a bubble somewhere that will have ABS warning lights flashing.
If the pads are almost worn out that means the caliper pistons have been exposed to road crud and when they are eased back in they can get damaged and start drawing in air. When you bleed up brakes manually by pumping the lever or pedal through its full travel there’s also a risk that the master cylinder seals might begin to leak for the same reason.
Radially mounted master cylinders often have a bleed nipple which makes life much simpler. If your bike doesn’t have this, it’s often better to fit an aftermarket double banjo with a bleed nipple.
Should I buy a Q ‘ringer’ back?
I purchased my bike just over a year ago but didn’t really get on with it so recently sold it on. The purchaser has established that the bike has a dodgy frame number, something that neither I nor he checked. I feel bad so I’ve offered to buy the bike back from him but he’s decided to keep it with a view to using it or selling it on. Where do I stand and what will happen if he does sell it on, it gets identified as a ringer and is traced back to me? Name and address supplied A I am assuming the bike is stolen, hence the dodgy frame number. If so, as you didn’t know at the time of purchase you will be fine and you have not committed a criminal offence. However, if you take it back that could be handling stolen goods, which is a criminal offence. The person who now has the bike should report it to the police and as he didn’t know either at the time of purchase he is also not guilty of a crime. However, now that he is aware, if he keeps it he is committing a crime.
Any refund payable will depend if you sold it before or after October 1, 2015. I am assuming after from your email but I don’t have exact dates. The Consumer Rights Act 2015 entitles the chap who bought it off you to a full refund. Presumably, however, this is for him to request. The point is you are in the clear and what the purchaser does or does not do is down to him. You cannot be liable due to your lack of knowledge. Whether you wish to alert the purchaser to the legal position and offer the refund is down to you. Just don’t buy it back!
