Sorry if I'm way behind on this, but , I couldn't sleep cause of Peripheral Neuropathy in my feet & legs, & I'm reading old forum posts , but I can echo Robbie's remark, I've had the best hydraulic disc setups, & the "Lowly mecanical drum", & once you lock the tire, All braking effort is gone, now you're relying only on tire skidding effort , which is sad , to say the least...
