Hi, I am David ! Thank you in advance for your help. I am 51 years old and did a lot of cycling in my teens then learnt to drive and gave up cycling. Until recently I went on 2 hour walks with my 2 Jack Russell dogs everyday but one of them ruptured 3 discs in her spine and is now limited to 30 minutes a day so I bought a Chinese made 3 wheeler new on Ebay and fitted an electric kit and strapped a dog crate on the back in place of the luggage basket so the fit dog runs along side and the injured one rides on the trike to and from the fields and forest and has a run around when we get there, both dogs happy. The trike has caliper brake on front wheel and drum on rear axle. I ve only used it a few times but find it very difficult to stop, Ive adjusted pads and shoes so they are within a fag paper of wheel and drum, Im wondering if they just need time to bed in or if i could purchase something more efficient in the way of brake material ? No matter how hard I pull on levers the trike just seems to slow down eventually whether Im using electric motor or just pedal power. Many thanks, David.
