Learn How To Bleed Your Car Brakes in the Perfect Way

Many people have heard mechanics discuss bleeding brakes while being serviced. Still, they need a fundamental understanding of how the brake system on a car operates beyond depressing the brake pedal and crossing their fingers.

Therefore, it is essential to understand how and when brakes should be bled. The brakes should be bled every two years or whenever the car’s brakes are serviced or replaced. You can perform brake bleeding by turning the bleeder screw and manually pushing any air bubbles out of the hydraulic brake lines. Just top off the master cylinder’s brake fluid as you go.

While it may be unsettling to discover that your brakes are soft or spongy as you approach a stop while driving, in some circumstances, this symptom can be quickly resolved by a brake bleed.

What Does It Mean to Bleed Your Brakes?

When someone says you need to bleed your brakes, they mean that you need to get rid of any trapped air that may have been added to the brake line system during brake repairs or as a result of a brake line leak.

Fluid pressure is necessary for a hydraulic brake system to operate correctly. Any air in the brake line can change the hydraulic system’s pressure and result in malfunctions or, in some cases, a complete failure. This is why it’s essential to check that your brakes are properly bled whenever a brake job is done. The air in the brake lines could cause your brakes to momentarily fail on the road if you replace them without bleeding them afterwards, leaving you responsible and, in some cases risking a fender bender.

That’s one of the main reasons you should only try to work on your car’s brakes with prior automotive repair experience or an experienced mechanic watching your back and double-checking your work.

When Should Your Brakes Be Bled?

Most mechanics advise flushing and bleeding the brake lines every two to three years as a preventative maintenance procedure. Even so, brake repair is a maintenance task that frequently goes unattended until it is necessary to replace the brakes because it is moderately complex. DIYers are less likely to attempt it.

Although brake lines only need to be flushed every few years, you should always bleed your brake lines to release any trapped air after replacing your brakes. This is because fixing a car’s brakes introduces air into the closed hydraulic system, which, if left unchecked, can result in mechanical failures and malfunctions.

How Do You Bleed Brakes in the Right Order?

To properly remove all trapped air from the lines, the brakes must be bled on the vehicle in the correct order. This is one technicality that can get many inexperienced auto-repair technicians into trouble when performing a brake job for the first time without the assistance of a qualified mechanic.

When bleeding the brakes, it’s crucial to start with the wheel farthest from the master cylinder and work your way closer.

The recommended brake bleeding sequence in rear-wheel drive vehicles is as follows:

  • Proper back wheel
  • Left-hand rear wheel
  • A right-facing wheel
  • Left-hand front wheel

The recommended brake bleeding procedure is as follows in cars with front-wheel drive or brake lines that are split diagonally:

  • Proper back wheel
  • Left-hand front wheel
  • Left-hand rear wheel
  • A right-facing wheel

If this brake bleeding procedure isn’t done correctly, air may still be left in the system, necessitating a restart. As a result, since brake bleeding is already time-consuming, it’s crucial to get it right the first time.

How Much Does Bleeding Your Brakes Cost?

Bleeding your brakes is reasonably priced compared to other auto maintenance tasks because no parts are replaced. You may only have to bear the cost of minimal brake fluid.

The fact that it is so inexpensive to have your brakes bled (and it needs to be done so infrequently) means that in almost all cases, it is better to leave this job to a mechanic who perfectly understands what they’re doing. This is because it is a somewhat complicated repair procedure, and doing it incorrectly can be a significant safety hazard. The fact that mechanics have the necessary tools to complete the task correctly makes performing a brake bleed easier.

Any amateur auto mechanic who is sincere about learning to work on their vehicles will eventually attempt a brake job. Still, if you’ve never done one before, you shouldn’t start a brake bleed without serious preparation. Before attempting this repair, you must review your car’s repair manual, speak with mechanics, and get assistance.

Final Thoughts:

Bleeding brakes are a maintenance job that is usually easier to leave to a professional mechanic because they have access to mechanical lifts and multiple people for manually bleeding brakes. Still, the procedure is simple as long as you’re careful and follow the steps precisely. Despite these potential challenges, DIYers can still bleed their brakes with the right supplies.
