Brake Pedal Goes to the Floor: Causes
A brake pedal that sinks to the floor is a serious safety issue. A Cranbourne West brake specialist explains.
What it usually means
A pedal that slowly sinks or goes to the floor usually means a hydraulic problem — a brake-fluid leak (at a caliper, wheel cylinder, line or the master cylinder), air in the system, or a failing master cylinder. Old, moisture-laden fluid can also boil and fade under hard use.
This is different from a slightly soft pedal — a pedal reaching the floor means braking is seriously compromised.
What you should do
Stop driving and get it checked or towed — this is an urgent safety issue, not something to “keep an eye on”.
We pressure-test the hydraulic system, find any leak or failing component, repair it and bleed the brakes properly.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
