Title: Quiz trivia
Post by: Bob Purton on January 28, 2014, 09:08:01 AM
Here are a couple of questions that came up at a quiz last week. Motorcycle related.

1. Which was the first Motorcycle manufactured to use disc brakes?

2. Where were HRD motorcycles first made?

Answers on a ten pound note please!

Correct!
The answer to the other question is slightly controversial.

Did Lanchester make a Motorcycle? Do not recall one.
Be one of racing bike manufactures without an engine budget at a guess. A bolt on accessory that might offer an edge. Being a racer it will be argued as to if it counts as the production version perhaps did not offer it.

Hi Richard. If you google it you will get the standard answer which is Douglas. It's disputed by some though because the Douglas set up wasn't quite the same as what you would expect a modern disc and calliper to look like. More of a wedge I'm told. If you find out more please let me know.

Just found this....

Just googled and got the 1922 Douglas answer ,wrong on HRD as well . Interesting Micro link on Discs - first U. S. 4 caliper on 1949 Crosley Hotshot !wonderful thing google but it ruions the fun and isn't always infallible - but which source is better ?

You can see why its disputed, not a true disc as it exerts downwards pressure on a small rim. Interesting though.

 And two further questions to pick your brains;  :)

 What was the last passenger car in the world to continue using a front drum brake?

 What was the last British car to be sold new with a starting handle?

 Both have links with microcars....

Good questions Stuart. Re the last car sold with front drums, not sure but my G-wiz was sold in 2007 and that has drums all round so that's my guess.

Would Trojan be correct for drums - they were still selling SOLID tired vehicles in the 50's. (60's ?) On second thoughts surely the Indian built Morris Oxford the Hindustan ? Starting handle the A35 or A40 ?- I know nothing  ;)

Dear Stuart

I think the Mopetta replicas Andy Carter builds are the last cars with a starting handle, otherwise known as a pull cord handle that starts the engine.

Dear Stuart

The front drum brake question was probably the Reliant three wheeler.

Well I appears that the  2013 Hindustan Jupiter. Is fitted with drums all around , but I think the Ambassador that I was thinking of has front drums and rear discs

What about the current Tuk Tuks? Are they drum?

Piaggio ape has a drum front brake but is it a passenger vehicle?

Stuart was there a clue in the question ? Drum brake not brakes ?

The Douglas brake has a disc rather than a drum, and seems to me to have a "male V' profile onto which the 'Female V" profile of the brake presses, therefore acting on both sides of the disc with concomitant mechanical advantage. I fail to see how anyone could dispute that it is a disc brake. To me that's like saying a V8 Engine is not an engine because its cylinders are not horizontally opposed.
