Clunking when braking after installing new brakes on front end

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! CLUNK! Is not what you want to hear after replacing brakes! Sounds like the new PowerStop brakes on your SX are causing a clunking due to the shims not fitting right or the lack of anti-rattle clips. Improperly fitted shims can let the pads move around, causing noise. Missing clips can also let the pads shift and clunk. Double-check that everything is torqued correctly and that the pads are seated right. Also, ensure nothing’s loose in the suspension. If the clunking continues, the shims or pad fit might need adjusting. Hope this helps! If it keeps clunking, drop by a shop and have them take a look.
