[Spridgets] Bad Breaking

Took a weekend off and am still catching up so I hope this is not redundant.

I use DOT 5 in my sports cars (not 5.1 which is short life race fluid).  
Water/moisture build up has not been a problem but I do follow good 
practice and replace the fluid completely every 4+ years.

Due to a 'helpful' mechanic, I had to remove some DOT 3 quickly and paid 
the price of new rubber in the master.  DOT 5 is NOT compatible with 
DOT3/4. If you do mix, clean (really clean!) and replace ALL RUBBER 
parts.  And for those with tandem systems, that also means the clutch 
rubber.

I am a little surprised to see DOT5 is not spec'd in Europe.  It has 
been readily available in Canada, and from several suppliers.  I will 
check into this further.

Cheers,
Martyn
