Brake disc problems

TrickyWicky

Gang,

Hit a slight problemo with the honda..

Need to measure the discs as there are two sizes. Only snag is that instead of leaving them on loose / floating the last person to touch them screwed the discs on tight with torx screws and presumably did so with an impact wrench / driver.

Can't get them undone :mad:

Any ideas?

Thanks peeps :beer:

If accessible, a bit of release spray on the thread (possibly from behind the hub). Leave overnight.

Use a manual impact driver to crack the screw off.

Which I don't have!

Hit the disc over the screw with a hammer. You won't damage the head of the screw as it is countersunk into the disc. Then should come undone no problem.

If you have a suitable torx bit and a breaker bar to use it with (not a rachet handle!) then put pressure on with the breaker bar while hitting it repeatedly with a big hammer. It has much the same effect as an impact driver

If it is really tight, put the ball end of a ball pein hammer on the head of the torx fixing and hit the other end of the hammer with another hammer to shock it. If it doesn't undo then, unless you have a hardened torx to use in an impact driver, you'll need someone with the right tools, or heat, to help you out.

I would advise buying the cheapest impact driver that you can.

Without using the proper tools you could do more harm than good

Or just drill the screws out

Which is exactly what I did on my Disco when I last changed the discs.

Impact driver is the best for removing them. They always get seized i found so i don't think the last person would put them in with an impact device.

Without one the only other option is a good quality torx on a 3/4 drive and some plus gas to see if that helps.

if still no good, then i'd drill them out.

Repeated light taps on the screw head can help release any corrosion that's holding the screws in place, without using too much force that could lead to damaging the screw head. I wouldn't expect them to be originally screwed on tightly, the screw is mainly there to help keep the disc in line while the wheel is being bolted up if it fits on the outside of the hub.

Not familiar with Hondas, but struggling to understand why you need to remove the disc just to measure it?
