A Right Grind
After 90,000 miles the grinding noise from the back of the car merited investigation:
The trick with this job is to use a piston pusher to push the piston back into the calliper - it needs to rotate too:-
The benefrit of asbestos free brake pads is that the discs appear to suffer somewhat. |
£75 later a new set of discs and pads are fitted. |

Banish the Blind Spot
Why are motorcycle mirrors so inadequate compared to the average car door mirror where blind spots are virtually eliminated? The ideal mirror would have a wide angle and a deep view too to capture more of the road behind. A failing with many mirrors is that they give a view through a letter box effect.
Here at NW Lab I have tried various improvements:
Riderscan:
The Riderscan is a hemispherical segment of mirror that provides a near 180 degree coverage. Unfortunately as mounted on the GS screen it provides an excellent view of mostly me and as it sits in the middle does not provide a logical scan sequence.
SAENG stick ons:
These resemble those stick-on blind spot eliminators but have a mounting system that allows them to be stuck independently on a fairing or windscreen.
Quite good when positioned correctly as they completely cover the blind spot. They do tend to wobble around a lot. Quite useful on dense motorways and for overtakes as they cover the shoulder check view without losing forward vision.
Finally I have tried to reposition the standard mirrors forward on crank arms (available from Wunderlich, Hornig etc.).

Crank Arms (extenders) - This has been the best - the mirrors are positioned forward and slightly outwards and give a wider effective view. |

Designers Should Get Out More
Why is the BMW specified, SHAD produced, Vario Top case 4cm to shallow to accomodate a typical full face helmet?
I have also shaved off the heads of the mounting bolts that protrude into the internal space.
This is an XL Shoei XR1100 |
I have now sold this helmet - a Shark Speed R fits but only just if a little compression is applied. |

A value for money Action Camera? SJ 1000
Recommended by Techmoan--> HERE
Trouble is, when mounted in the waterproof case there is no way to switch the camera on and off.
I removed a plunger switch from an old go pro case and drilled a 2.5mm hole in the SJ 1000 case. It seems to work fine but is probably not waterproof to 30m.
