When they wear or get **oil-soaked**, the brake stops holding and needs new shoes. Many vehicles with rear disc brakes hide a small drum brake inside the center of each rear rotor, called a drum-in-hat. Those small emergency brake shoes hold the car when parked. Route 66 Auto Repair in Upland replaces them when they are worn, glazed, broken, or soaked by an axle seal leak. We measure the shoes and the drum surface inside the rotor, take photos, and give you a written estimate before replacing anything. ## What are the signs of worn emergency brake shoes? - The parking brake holds weakly even after adjustment - A scraping or clunk from a rear wheel when rolling slowly - Oily residue on the inside of a rear wheel - The parking brake was driven with it on, causing a burning smell - Rotor surfaces look fine but the parking brake does not hold ## Why do these small shoes wear out? In normal use they barely wear, since they only clamp when the car is still. Wear comes from driving with the brake partly applied, from a seized cable, or from rust building up on the drum surface inside the rotor. Heat from an overheated stop can also glaze the lining. Oil is the other enemy. On many trucks and rear-drive cars, a leaking axle seal soaks the shoes. Soaked linings cannot be cleaned back to full grip, and the seal must be fixed at the same time, or the new shoes soak too. Seal work may lead into [drivetrain service](https://route66autorepairshop.com/drivetrain-and-additional-mechanical-services). ## Our emergency brake shoe replacement process 1. **Remove caliper and rotor:** The rear caliper and rotor come off to expose the small shoes. 2. **Measure and photograph:** Shoe lining and the drum surface inside the rotor are measured and photographed. 3. **Replace shoes and hardware:** New shoes go on with springs and adjusters as quoted, and contamination sources are addressed. 4. **Adjust and test:** The shoes are adjusted, the rotor and caliper refitted, and hold and drag are checked on a road test. ## What's included - Caliper and rotor removal and refit - Shoe and drum surface measurement - New shoes and hardware as quoted - Check for axle seal or brake fluid contamination - Parking brake adjustment - Hold test and road test ## Need-now or need-later? **Need now:** - Oil-soaked shoes with an active seal leak - Broken shoe or spring rattling inside the rotor **Need later:** - Thin but intact shoes with a working hold - Replacement timed with a planned [brake rotor replacement](https://route66autorepairshop.com/brake-services/brake-rotor-replacement) ## How pricing and timing work Access is the main cost factor. Some rotors come off easily; others are rusted to the hub or need hub removal. If the drum surface inside the rotor is worn past spec, a new rotor may be needed. That goes on the written estimate before we proceed. AAA members get 10% off parts and labor, up to $75. We schedule the job when the board can hold it and text you if timing slips. ## Aftercare Some makers call for a short bedding-in procedure for new parking shoes. We do it before you leave and explain it at the counter. If you want the rest of the system reviewed, book a [brake system inspection](https://route66autorepairshop.com/brake-services/brake-system-inspection). ## Frequently asked questions ### How do I know if my car has drum-in-hat parking brakes? If your car has rear disc brakes and a cable-operated parking brake without a caliper lever, it probably does. Looking through the wheel you may see a round hat section on the rotor. We can confirm in a minute. ### Can you just adjust the shoes instead of replacing them? If the lining is still thick, yes. If the lining is thin, glazed or contaminated, adjustment will not restore the hold. We measure and show you which applies. ### Should I replace the rotors at the same time? Only if the drum surface inside or the braking surface outside is worn past spec. Since the rotor has to come off anyway, combining jobs can save labor when both are due. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
