Front Disc Brake Slide Pins - Question - Toyota Yaris Forums

CoryM · 06-13-2016, 02:46 AM

The rubber tube on the pins are just there to reduce the chances of having a rattle, or clunk. Without them, the calipers can audibly rattle on bumps, or when applying brakes. Pins that have the rubber tubes are more likely to seize up since the rubber is sticky. Make sure to lube them well.

It won't hurt anything for it to be missing. Chances are the Toyota clearances are tight enough to keep it from rattling. However, the rubber dust boot on the outside is definitely critical to keep the pins moving freely and not wearing the bores from dirt.

Cheers.
