Which side of these (absolutly terrible) calipers is the leading edge? I’m being stubborn about thowing this bike together with zero money.
Not sure what you mean by leading edge here. Those are calipers for a pocket bike, e.g. 50cc motorcycle. If this is for a pocket bike, you might have better luck on a motorcycle forum. That said, each caliper can only fit in one direction when the rotor and wheel are installed. The actuation arm dictates which is front and rear (or left and right for dual front rotors) by where the cable is coming from on the bike. Provided those calipers aren’t seized and the actuation arms are pictured in the neutral position, the cable must pull the arm away from its neutral position, i.e. counter-clockwise and clockwise respectively (L-R, as pictured).
Maybe you know this, but just in case: you’re missing a cable stop on the left caliper and you’ll need cable-fixing bolts. Also, I get that you’re trying not to spend any money, but check the brake pads before installation. Even if the pads have a bunch of material left, looking at those calipers, my guess is that the pads are contaminated or worse glazed. You will never get the squeal out of contaminated pads.
Thanks, by leading edge i mean which way should a disc be passing the pads. the e-scooter they were attached to was so poorly built (and in bits when i got it) that i couldn’t trust they were installed correctly anyway. So that is backwards from what i expecting, but it make sense, the adjustment knobs (knurled thingies on the left and right of each caliper) bring the trailing edge of the pads closer to the disc, alright some brackets and welding to do.
and probably even more after i discover these don’t work at all and i give in a buy something else. if it worth doing at all, might as well do it twice…
The “leading edge” refers to the front part of your bike’s brake pad that touches the wheel rim or disc rotor first.
It looks like those are center pull breaks. Here is a vid about center pull break adjustment.
thanks for the reply, wrong brakes but thanks anyway.
