This Starter Kit includes everything you will need to drastically increase the number of brake fluid and coolant exchange services you are performing. Each kit includes 100 brake fluid test strips and 100 coolant test strips. We recommend testing every single vehicle over 30K miles. On average 1 out of 2 of those vehicles will be in dire need of a brake fluid or coolant exchange. Your counterman can then use the scientific proof provided by the test strip to explain to the customer why they need to have their fluid changed. To make selling the exchange even easier you will receive 2 sales cards. Each card is made with the thickest, most heavy duty laminate available. This means you can clean the card and use it for years to show what happens when we neglect brake fluid and coolant.
