I have a follow-up question about my Raleigh Sports brakes. A local bike guy who specializes in 3-speeds helped me fix the rear brake and swap out the old odd for some newer ones, but when I went for a ride today, I noticed that the rear brake did NOTHING to actually stop the bike. It may have slowed down a bit but it certainly didn't "brake" the bike. The front brake worked fine. I co press and the bike stops, but when I compared and used the rear brake alone, it was inept. I typically use them together, applying more pressure to the front brake than the rear, having read that's the way to do it, but I'm curious if my rear brake is actually functioning properly, given of ineffective it is at braking by itself.

Thanks all!
