My Brake Pedal Depresses to The Floor, Why?

If everything is ok with your car, your pedal will not depress all the way down to the floor when you apply brakes.

A brake pedal that sinks all the way to the floor could indicate a problem with the brake master cylinder or it could be due to a brake fluid leak. In all situations, a detailed vehicle health check is necessary; after the problem has been correctly identified, you may move on with the necessary repairs. For your safety, do not put it off for too long.

Any problems with your braking system may be hazardous to both you, your passengers and other road users. If your vehicle exhibits any of the following symptoms, then we highly recommend that you speak with one of our qualified technicians. It’s imperative, you’re not responsible for any accident by neglecting to maintain your vehicle.

What can cause the brake pedal to sink to the floor?

As we previously alluded to, there are two basic explanations for why this could be taking place. The first is a brake fluid issue. This suggests that a brake fluid leak in the braking system may be to blame for the drop in brake fluid pressure. The second, could be a problem with the brake master cylinder with the fluid getting past the seals. In such instance, even if you slam on the brakes, your braking system will not react as expected or will not react at all.

How to identify and correct a sinking brake pedal issue?

We’ve highlighted two of the causes of brake pedal sinkage. Here is an insight into how to diagnose the issues, however, we would always recommend seeking professional help when attempting to make any repairs:

• Start by examining the brake fluid level.
• If the brake fluid level is optimal, then you do not have a brake fluid leak issue on your hands.
• On the other hand, there is a leak problem if you discover that your brake fluid levels are low or if you are entirely out of brake fluid.
• The first step is to inspect all the brake lines coming from the wheels to see if there are any leaks.
• The wheel cylinder must be changed, or the brake lines must be repaired if you discover a leak in the brake lines.
• Typically, your brake warning lights may come on if there is a brake fluid leak. If this does not occur and there are no outward indications of a brake fluid leak, your brake master cylinder may be at fault.
• There are two sets of seals on the braking master cylinder. An interior leak may occur if the seals are compromised or worn out. The brake master cylinder will need to be changed if this is the situation.
• If your vehicle is equipped with an antilock braking system (abs), a leak in the abs unit might cause the brake pedal to sink to the floor.
