Pads only, or pads and rotors
This is the decision at the center of most brake jobs, and it is where the price difference lives.
Pads are the wear item. Rotors wear too, more slowly, and they also distort with heat and lose thickness every time they are machined. A rotor that is below its minimum thickness, grooved, or distorted enough to pulse the pedal is at the end of its life, and new pads fitted against it will not bed properly, will not last as long, and may bring the pulse straight back.
Fitting pads to a rotor that should have been replaced is not a saving. It is the same job again sooner, with the first set of pads thrown away.
A rotor in good condition is a different matter, and should keep working. The inspection is what tells you which case you have, and it should be a measurement rather than an opinion.
What the inspection covers
Pads, rotors, calipers, hardware, hoses and fluid, as a system. Caliper slides that have seized are a common finding and produce uneven pad wear across an axle, which looks like a pad problem and is not.
Brake fluid is checked too. It absorbs moisture over time regardless of mileage, which lowers its boiling point and corrodes components from the inside.
Symptoms and what they usually mean
- A squeal that fades after the first few stops is often surface rust overnight, and normal.
- A squeal under braking that does not go away is usually wear.
- Grinding means the pad material is gone and the repair is growing with every mile.
- A pulse through the pedal from speed usually means rotor condition.
- A pull under braking can be a caliper, and can be suspension, handled at the same store.
