Hello guys, I have ordered this disk lock system last week and it should be with me tomorrow. http://roadlok.com Basically it fits on the front brake caliper (left hand side on the MTS) and requires the two caliper bolts to be removed and replaced with the provided (longer) ones. I have tried yesterday to unscrew the original caliper bolts however they are fitted very tight. Any suggestions? Is there something wrong which could happen by unfitting and refitting the caliper? Thanks!
Probably just not been undone for some time. Make sure the Allen key is a good fit in head and in completely. Use a torque wrench or a bit of pipe for a extension for a bit more leverage. Should be no reason why they don't come straight out unless they have been in for along time and there is a corrosion issue. Like the look of the lock.Anything you don't have to carry round is good.
They are probably just overtorqued. Maybe someone has used threadlock on them (I think you just use grease on the bolt threads).
Thank you so much guys, the bike is fairly new (Jan 2019) so I think never been undone so far. I will try with an extension. Quite excited about the lock, hopefully it's a good product (looks like it).
Use an Allen key socket rather than an Allen key, like this https://www.ie.screwfix.com/teng-tools-ttbs35-mixed-metric-af-bit-socket-set-35-pieces.html Use a good quality one, not a cheap chinese one, that fits snugly and tap it him with a hammer to make sure it’s fully seated. Use the longest socket wrench you have or a breaker bar. Sometimes a sharp tap on the breaker bar with a hammer, whilst holding the Allen socket in place so it doesn’t slip, can shock it free. I doubt it’s corroded if the bike was new in Jan, just, as said above, overtorqued. GL
The problem is more likely to be thread lock rather than over torqued or corrosion. Ducati use thread lock on all critical bolts and it can difficult to break the bond, a long, steady application of force can work better than short, sharp shocks. Heat usually helps, maybe the use of a heat gun will help but maybe not a good idea to use a blow lamp. Also, I not recommend using a torque wrench to undo bolts.
Personally I'd stay away from the use of a heat gun near brake calipers. I'd just up your torque by using a breaker bar or longer ratchet.If memory serves, I think calipers are torqued to about 38nm, so not a massive amount, they will loosen.
Thanks guys. Yesterday I tried with an Allen key - will give it another go today with an Allen key socket and report back - fingers crossed!
The socket will likely do the job. Worst case, rattle gun it with a socket but highly unlikely you will need to take it that for. Allen keys are kiddy tools in comparison, once you use a proper Allen socket set.
Likely they have been glued in (and hopefully not cross threaded). Not recommending anything, but my approach would be Allen key bit & brute force.
So guys I've just given it another go and....NO WAY!! I think they are glued - shall i ask the dealer for help? I'm quite confident I'll be able to fit the lock on my own - just need help in unscrewing
Great piece of kit Roadlok, I use one on my Multi, as bladders says make sure you use correct spacers to get the lock pin to engage in the disk easily and make sure bracket clears wheel weights etc Caliper bolts came out easily on mine with a good quality allen hex bit and breaker bar, sometimes the bolts can get seized in the callipers and it’s recommend to apply grease to the bolt shanks to prevent further corrosion, so it maybe some corrosion issue you have making them tight, but I would have thought rather unlikely on a 2019 bike..? Get a good socket and purchase on the bolts and they will come out
Just a thought, in case you haven’t. Sometimes a smidge tightening helps break the thread and allows it to loosen.
What length wrench did you use? Try a 24" breaker bar (or longer). Trust me, as I refurbish a 20yr old 748 I've had some buggers to undo
+1 with, make sure you use the correct spacers and it clears any wheel weights. My caliper bolts came off fairly easily with a socket allen key and bar.
Had plenty of clearance on the rim but didn't factor in the wheel weights. These, I later noticed, then had a thin skim across a small part of their width Have since fitted new tyres and put the weights on the other side...
