Do tubeless tires and sealant eliminate this risk?
On long descents that are moderately steep. I alternate front and rear braking and can avoid a blowout. But on shorter steep hills stopping quickly is required.
(1) No, as others have said. It will potentially make the problem worse.
(2) This is exactly why I insisted on getting hydraulic disc brakes. Those grades are prevalent where I live, and I am a bit paranoid on descents, and ride the brakes more than I rationally need to. If there was ever a compelling reason to get a new bike, it is this.
