Check a brake caliper replacement quote

What the job usually involves.

The caliper is the clamp that squeezes the brake pads against the rotor. Replacing one usually means disconnecting the brake hose, unbolting the caliper, fitting the new unit, reconnecting the hose with new sealing washers where the design uses them and tightening the bolts to the manufacturer's torque. The system is then bled to remove air, the pedal is checked and the car is road-tested.

Pads that brake fluid has leaked onto are normally replaced rather than cleaned, and pads are usually replaced in axle sets. Whether the whole system is bled or only the wheel that was opened depends on the vehicle's service information; on some vehicles with anti-lock brakes a scan-tool procedure is part of the bleed.

Rear calipers on many newer vehicles include an electric parking brake motor or a mechanical parking brake mechanism. That can change the part, the procedure and the time needed, and some electric parking brakes need a scan-tool setup after the new caliper is fitted. A front caliper quote and a rear caliper quote are rarely interchangeable.

What a complete written quote should state.

• Which calipers: front or rear, left, right or both.
• Whether each caliper is new or remanufactured, with a brand or part number.
• Whether the unit is loaded with pads or bare, and whether the bracket is included.
• Any hose, sealing washers or hardware replaced.
• Brake bleeding and the fluid type used.
• The core charge and the terms for getting it back.
• Labor as hours or a flat price, shop supplies, disposal fees and tax.
• The written warranty on parts and labor.

What changes the total.

The number of calipers is the first thing to check: one side and an axle pair can look like similar jobs on a short quote. Whether pads, rotors, a hose or the bracket are added changes the total as much as the caliper itself. If a full fluid flush is quoted on top of the bleed, part of the labor may overlap, so ask how the two are charged.

The vehicle matters too. Rear calipers with a parking brake mechanism, larger multi-piston calipers and electric parking brakes that need a scan tool to retract can all change parts and labor. Unit condition, the core charge, the local labor rate and tax account for the rest.

One caliper or the pair, new or remanufactured?

Replacing only the caliper that failed keeps the bill down; replacing both on the axle keeps the two sides matched. Practice varies between shops, so ask which one the quote assumes and compare quotes that make the same choice.

Many replacement calipers are remanufactured: a used caliper body cleaned and fitted with new seals and, where needed, new pistons, usually sold with a core charge. Federal guides on rebuilt and used automobile parts say that selling such a part without clearly disclosing it, including on invoices, is deceptive. Ask for the condition to be written on the quote.

When a second opinion is worth it.

• Both calipers on an axle are recommended with no reason stated for the second one.
• The quote says “caliper” without saying new or remanufactured.
• A core charge appears but the refund terms are not written down.
• The quote does not mention bleeding the brakes after the caliper is replaced.
• Calipers are recommended with no description of a leak, a seized piston or uneven pad wear.

If the brake warning light is on, the pedal feels soft, the car pulls when braking or a wheel smells hot, have the brakes inspected promptly. A second opinion should not mean driving on brakes you are unsure about.
