Common Brakes

Brake disc warping

Symptoms

Judder through the steering wheel or brake pedal under braking.

Cause

Discs warp from heat, particularly if the brakes are used hard then the car is stopped (heat concentrates at the pad contact point). Age and corrosion compound the problem.

Fix

Machine the discs if they're within thickness limits.

Replace if they're too thin or cracked.

Budget $200-500 per axle including pads.

Critical Brakes

Brake servo failure

Very hard brake pedal, poor stopping performance. The car feels like it has no brakes.

Common Brakes

Caliper seizure

Uneven braking, pulling to one side, excessive heat from one wheel, brake drag.

Minor Bodywork and Rust

Sill corrosion (structural)

Outer sills bubble and perforate. Inner sills rot silently behind trim. The car's rigidity decreases, doors sag, gaps become uneven, and the body flexes over bumps.

Minor Bodywork and Rust

Floor pan corrosion

Floor pans rot from underneath or from above (water sitting under carpets). In severe cases, you can see the road through the floor.

Common Bodywork and Rust

Rear wheel arch and lower rear quarter corrosion

Rust appears at the bottom of the rear wings, around the wheel arches, and in the lower panels between the wheels and boot.

Common Bodywork and Rust

Boot floor and spare wheel well corrosion

The boot floor rusts through, the spare wheel well fills with water, and the rot spreads to surrounding panels.
