I find one advantage to having left/right brakes is applying force differently to each side helps with fast turns. So let's say I'm going fast and need to turn right. I'll lean into the turn and apply some braking force to the right brake, while applying no or little force to the left brake.
After burying my chain ring into the asphalt, during emergency breaking, the third time; i put a disc break on the rear wheel as well. I keep it a bit softer than the front. Not sure if it helps but i haven't smacked my new ring guard into the pavement yet.
No mention of slamming crank sprocket into pavement or flipping over downhill offroad on tadpoles? Two hydraulic rear brakes on one hand lever on my delta trikes.
You usually don't need to change your chain unless you see a problem with it or it wears out. We recommend using a chain checker to check. Too much lube can cause your chain to become wet and sticky. This can cause them to attract dust and dirt that will wear out the chain.
I love disc brakes when they come into my shop. Why? $$$$$. Drum brakes…rarely touch them. 90% of riders don’t need disc brakes...too bad more trike manufacturers do not offer drum brakes...I also have had customers get thrown off their disc brake trikes from slamming on the brakes and doing a reverse wheelie...
95++% of riders do not need tadpole sportscar handling either! Scenery sightseeing, nature viewing and exercising do not require tadpole "sportscar" handling. 2WD and maximum suspension under rider's torso on delta planform trike. 70-yo, limited-mobility handicapper here.
