It is easy for one to compromise on nearly all the other car parts when they wear off. When it comes to brakes however, there is usually no compromise. You have no choice but to replace them. Fortunately for brakes and especially for the Porsche model, there are usually tale tell signs that can let one know it’s time to consider replacement. But before buying a new set of brake pads or driving your car to a mechanic for its regular inspection, it is important to first understand how brakes work. Only then can you decipher the aforementioned tale tell signs with precision.
How They Work
Nearly all Porsche models use disc brakes at the front. The concept behind how the Porsche brakes work is easy. A hydraulic brake caliper pushes brake pads on a steel disc to slow down a moving vehicle. There is always a pad on each side of the brake disc clamped against each other by the hydraulic force of the caliper. Note that some cars, especially high end sports cars use carbon ceramic discs instead of steel. Either way, steel stands out as the most common option for most cars.
The Tale Tell Signs
Always use the Listen, Feel, See and Check formulae. Drive around at a moderate speed then brake gently. Squeaking and grinding sounds are a red flag. Feel the brake pedal as you put your foot on it. Does the pedal feel fade or soft? Do the brakes pulsate or pull? The seeing part is easy. All you have to do is check if the ABS light is on. The checking is easy too. Check if your car has hit the 12,000 mile. Check too if it has been 12 months since you last replaced your brake pads.
Listen To What Your Car Tells You
Porsche models are smart cars. Their brake pads feature in built wear sensors. That means your Porsche will trigger a warning light on the dashboard each time your pads wear out. Do not ignore the warning light as it only turns on when the pads have worn out the lowest minimum level.
Know The Right Pad Thickness
Take time to visually check brake pad thickness. This should be easy if you have alloy wheels as they make it easy for one to look through wheel spokes at the caliper. Be keen on the thickness of the pads where they come in contact with the disc. The brake pad friction material should be at least 3mm thick.
Keep in mind that this method should not be used on its own. Use the aforementioned criteria as well. The main draw back with visually inspecting the thickness of your brake pads is the fact that not all pads will have the same thickness. You can therefore easily assume you have perfect brake pads just because one brake pad appears to be perfect. Be sure too to have a car expert assist you with the visual inspection.
