Equipment failure

I have to report a rare failure of the Mk1A GingerScope.

Those of you familiar with this device will know it to be the most
powerful fault-finding device known to man. Any motorcycle parked within
the Mk1A GingerScope's sphere of operation is subjected to a deep scan,
revealing a myriad of small but annoying defects of which the rider was
hitherto blissfully unaware.

I took the Pan over to Flitwick the other day. The GingerScope took a
deep drag on its rollup, beeped twice, and pronounced the rear tyre
fucked. It wasn't wrong either.

It failed, however, to spot that so were all three sets of brake pads.

Oh well, it's only money.

The rear pads are still binding a bit, which is a pain. It's had new
seals and a shedload of copper grease, so I'm beginning to suspect the
master cylinder. I'll have a furtle in a minute and check the return
hole.

If the pistons are lubed with copper grease then the seals don't grip
correctly. This sound counter-intuitive but the seals do have to grip
slightly as it's only the relaxation of the seals, as the fluid pressure
drops, that pulls the pistons back and creates clearance for the pads -
unless the disc is warped and knocks the pads back.

 

Can you use a Dodgy Gingerscope cert in place of an MOT?

 

Wicked Uncle Nigel says...

I've got to a stage where I only take my bike out when he's not around
or asleep. He finds fault with things that I'd never even thought of and
my subsequent ride is then filled with fear of death and destruction. I
am happy to be blissfully unaware of whatever trivial fault he might
have found...and I haven't died yet.

 

I'd just point at his collection of bikes and sneak off while he wiped
away his tears.

 

Out of interest, did you have the Bindit out of his range before the
suspension collapse?

 

Grimly Curmudgeon says...

He hasn't looked it over for some time.

Oh aye, the pistons aren't lubed, just the pins (single sided calipers,
see).
