Check the listing for details. Laser Tools Twin Function Brake Punch 5.5mm 7868. Condition: New, Made in Unknown. Listed at 30.46 USD. A specially designed, 5.5mm pin punch particularly suited to use on vehicle brake pad pins where the pins are a tight fit and the ends of the pins at risk of spreading out (mushrooming) and jamming in the caliper which can happen when standard flat punches are used. This issue is often seen with Brembo type calipers. The punch is made up of 2 punches in one, the short punch has a specially machined, concaved end that ensures the initial force of impact is concentrated on the circumference of the pin to significantly reduce the chances of mushrooming. Once the pin has moved, the longer pin can be used to continue the removal process. The simplest and safest way for our customers to pay for items is through PayPal.
