How to Pump Brakes After Changing Brake Pads: The Essential Guide
If you’ve ever undertaken the task of changing the brake pads on your vehicle, you know the sense of satisfaction that comes with it. But there’s one crucial step that can’t be overlooked before you hit the road again – pumping the brakes. This action ensures your brake system is primed and ready to perform at its highest ability. In this guide, we’re diving into the why and how of pumping your brakes after swapping out those pads, ensuring your safety and the longevity of your repair.
Why Pump Brakes After Changing Brake Pads?
When you change your brake pads, air can enter the hydraulic system. Even the slightest amount of air can lead to a spongy or soft brake pedal feel, reducing the effectiveness of your brakes. Pumping the brakes helps to remove any air pockets that might have found their way into the system and re-establishes solid pressure throughout the brake lines.
Step-By-Step Guide to Pumping Your Brakes
Here’s what you’ll need to do after changing your brake pads to make sure your brake system is properly primed.
Step 1: Check Brake Fluid Levels
Before you start pumping the brakes, check the brake fluid level in the master cylinder reservoir. If it’s low, top it off with the correct type of brake fluid for your vehicle. This is necessary because as brake pads wear down, the fluid level can drop, and replacing the pads could require more fluid.
Step 2: Secure Your Vehicle
For safety’s sake, make sure your car is in “park” or in gear if it’s a manual, with the parking brake engaged. The last thing you want is for your vehicle to move unexpectedly while you’re pumping the brakes.
Step 3: Pump the Brake Pedal
With the engine off, press down on the brake pedal repeatedly – about 10 to 15 times should be sufficient. This builds pressure in the brake lines. On the final press, the pedal should feel firm underfoot, indicating that you’ve built enough pressure in the system.
Step 4: Bleed the Brake Lines If Necessary
Sometimes pumping the brakes isn’t enough to eliminate all the air. If the brake pedal still feels soft after pumping, you may need to bleed the brakes. This should remove any remaining air bubbles from the brake fluid in the lines. You can do this at home, but if you’re not confident, this is a procedure your mechanic can perform for you.
Step 5: Check the Brake Fluid Level Again
After bleeding your brakes or pumping them, check the brake fluid level again. If it’s gone down, top it off once more to ensure it’s at the proper level.
Step 6: Test Drive
Once you’ve finished with the initial pumping and any necessary bleeding, it’s time for a test drive. Start slowly and test your brakes in a safe area before getting up to speed. Pay attention to the feel of the brake pedal – it should be firm, not soft or spongy.
Common Mistakes to Avoid
- Overlooking the Brake Fluid: Neglecting to check or top off the brake fluid can result in weak braking performance or damage to the system.
- Skipping the Test Drive: Without a test drive, you won’t know if the brakes are operating correctly or if further attention is needed.
- Nort Securing the Vehicle Properly: Working on brakes is serious business, and failing to secure your vehicle could result in injury or damage.
FAQs on Pumping Brakes
Q: Can I damage my brakes by pumping them too much?
A: Generally, no. Pumping your brakes is a normal and expected procedure after changing the brake pads. However, always ensure that your car is secure and that you’ve checked the brake fluid level to prevent other issues.
Q: Do all types of vehicles require brake pumping after pad changes?
A: Most vehicles will benefit from this practice after a pad change to ensure safety and performance. However, some modern cars might have specific reset procedures for their brake systems, so check your owner’s manual or consult with a professional if you’re uncertain.
Q: How do I know if I need to bleed my brakes after pumping them?
A: If your pedal is still soft or spongy after pumping, this indicates that air is trapped in the system and bleeding is required.
Wrapping Up
Changing your brake pads is a satisfying DIY task but remember that safety comes first. Pumping your brakes after the change is a vital part of the process, safeguarding you against unpredictable braking performance. Take the time to perform these steps methodically, and you’ll extend the life of your brake system while ensuring the safety of everyone on the road.
Remember, if you’re ever in doubt or encounter unexpected issues, consult a professional. Your local mechanic or a certified technician can provide insights or assistance to ensure everything is functioning as it should.
Drive safely, and happy braking!
