Toyota Vitz: Rear Brake Drum and Wheel Cylinder Corrosion

Rear Brake Drum and Wheel Cylinder Corrosion is a common brakes fault on the Toyota Vitz on the 1999–2005 cars, and we rate it major. Putting it right costs $350 to $900 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 27 documented faults on the Toyota Vitz.

What you are looking at

No photograph available

We do not hold a verified photograph of the Body corrosion yet. We would rather show none than show a picture of a different part.

What goes wrong

XP10 Vitz models imported to New Zealand are now 20–26 years old and the rear drum brake assemblies suffer significant corrosion in the coastal and high-rainfall conditions common in NZ. Brake drum internal surfaces corrode and become grooved, wheel cylinders develop internal seal failure and external weeping, and the drum self-adjuster mechanisms seize in the corroded state. Corroded or seized wheel cylinders cause uneven rear brake bias, dragging brakes, and brake fluid leaks that contaminate the brake shoes. On vehicles that sat unused or were stored poorly this issue can render the rear brakes functionally ineffective.

What you would notice

Pulling to one side under braking, especially from low speed
Grinding or scraping sound from rear wheels when braking
Brake fluid weeping or wet residue visible behind rear wheels
Handbrake requiring excessive travel to hold vehicle on gradient

How to check it

Where to look. Rear axle drum brake assembly — drums, wheel cylinders, shoes, and self-adjusters

Check wheel cylinder rubber boots for cracks and squeeze gently for fluid weeping. Inspect brake shoes for contamination with hydraulic fluid or grease. Manually operate the self-adjuster to confirm it moves freely and is not seized solid. If a workshop inspection is possible: Remove rear wheels and inspect drums for scoring, deep corrosion, or out-of-round.

Parts involved: Body corrosion.

What it costs to put right

$350 to $900 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“When were the rear brakes last inspected or replaced?”
“Has the vehicle passed a recent WoF without brake-related advisories?”
“Has the vehicle been stored outside or near the coast?”

Now check the Toyota Vitz you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Toyota Vitz buyer questions

Is rear brake drum and wheel cylinder corrosion serious on a Toyota Vitz?

We rate it major and common on the Toyota Vitz. XP10 Vitz models imported to New Zealand are now 20–26 years old and the rear drum brake assemblies suffer significant corrosion in the coastal and high-rainfall conditions common in NZ. Brake drum internal surfaces corrode and become grooved, wheel cylinders develop internal seal failure and external weeping, and the drum self-adjuster mechanisms seize in the corroded state. Corroded or seized wheel cylinders cause uneven rear brake bias, dragging brakes, and brake fluid leaks that contaminate the brake shoes. On vehicles that sat unused or were stored poorly this issue can render the rear brakes functionally ineffective.

How much does it cost to fix on a Toyota Vitz?

$350 to $900 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Toyota Vitz years are affected?

Our research records this fault on the 1999–2005 Toyota Vitz. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
