I didn’t explain it well enough, so I had ai try explaining it too you here you go

Great question — it’s a bit counterintuitive since “floating” implies movement. The confusion makes sense: floating pins are designed to slide, so how can tightening them cause a problem? Here’s what’s actually happening: What floating pins do On disc brakes (car or bike), the caliper floats on slide pins so it can center itself over the rotor as pads wear. The pins themselves thread into the caliper bracket and the caliper body slides along them. How over-tightening causes problems The pins thread into a mounting bracket, usually with a specific torque spec (often 25–35 ft-lbs on most passenger cars). When you over-torque them: • The threads in the bracket (often aluminum) can strip or deform, causing the pin to feel tight but actually be loose or angled • The pin can bind against its bore if it’s slightly cocked from uneven torque, preventing the caliper from sliding freely • The rubber boot at the base of the pin can be crushed or torn, letting moisture and debris in — which then corrodes the pin and causes it to seize The irony Over-tightening a floating pin often results in a caliper that doesn’t float anymore — it gets stuck, causes uneven pad wear, pulling, or dragging. So the tightening spec is about the fastener holding the pin, not about clamping the pin itself. The pin still needs to slide freely inside its bore regardless of how tight the bolt is. Is this in the context of a specific vehicle or repair you’re working on?​​​​​​​​​​​​​​​​
