Anyone else remember the 1980s, when all bike engines seemed to be assembled using Philips-head M6 screws in a huge range of lengths so that exactly the right screw had to go back in every position, and because they passed through so much alloy they'd invariably corrode into the engine. You'd hit them with an impact driver and the head would shear off, leaving 80% of the screw welded into its bore...

Oh yes, an RD50M.

Correct. I find that a lot of modern fasteners are a bit on the rubbish side - and once they're well 'in there' after a period of time, some heat cycles, and a bit of corrosion, they're a bugger to remove without damaging them.

There are some schools of thought that go with replacing safety-sensitive fasteners once removed - i.e. brake caliper bolts are a 'one shot consumable' and I can kind of see that logic.

If a fastener is well-fastened into a thread, then if you try to remove it with a normal ratchet - then all that happens is that the head of the fastener chews up with the torque long before the thread lets go.

With an impact driver as your first tool of choice, the impacts are working directly on the threads, via the shank, in order to break that seal.

Your point about the tool is also correct - with a cheap 6mm hex bit that might not fit perfectly, then it might be a bit pointless, and lead to the usual damage to the fastener. I am lucky, I have invested in nice tools over the years (mostly Snap-On) and so the tools fit the fasteners perfectly, and hence I get a good result every time.

HTH.

I took my callipers off today just to give them a clean up general maintenance.

Couple of the bolts started to slightly round when putting them back on. Where the fk do Suzuki buy this rubbish from.

Tbh it's a great bike to ride but I've never seen build quality this poor

Are you using a torque wrench, did you remove the old lock tight compound before putting them back in and are you using sockets with 6 flats or one with 12 or more?

I only ask as if the bolts have just started to round off then they were put in in the first place correctly without damage. They may be made of cheese but I guess they're up to the job if suzuki got them in in the first place without damage.

Aye all done correctly with the tourque wrench, tbh im not sure what sockets I used most of my tools are in my parents garage ive just got a few bits n bobs here so It might have been a 12 point socket.

Remove the Loctite you say, non on them. Whichever spaztard did the brakes last decided it was a good idea to put grease on the bolts.

Its all sorted now though.

One other good tip that worked with me and it really came out of utter deperation when i was once trying to split a caliper,the very last bolt was a sod,seized solid!After lots of swearing,throwing random items i thought sod it,i battered on a socket over the top of the entire bolt head,a tight fitting socket with the star shaped inside(not a hex one)and to my utter amazement it gripped down on the bolt and broke free!
