Mission Muffler & Brake
Mufflers, exhaust work and brake repair on Hayward's Mission Boulevard, with Saturday hours and a courtesy shuttle.
About
Mission Muffler & Brake keeps a shop at 21011 Mission Boulevard in Hayward, the address the chamber has on file and the one the shop publishes on its own contact page. Mario Chavez is listed as owner in the chamber's records. The name spells out the specialty: exhaust systems and brakes, two jobs drivers tend to put off until a rattle or a squeal forces the issue. The shop's website says it has served the Bay Area for more than 25 years.
Exhaust, brakes and the rest
Those two lines of work are what the shop's own pages name. On the exhaust side that means mufflers, pipes, hangers and the joints between them, where leaks usually start as a deeper note at idle and can eventually let fumes into the cabin. On the brake side it means pads, rotors, calipers and fluid.
A muffler and brake shop of this kind also tends to handle catalytic converters and routine under-car inspections, but ask about anything beyond the two headline services before you bring the car in.
Dropping off the car
Weekday hours on the contact page run from 8:30 a.m. to 5:30 p.m., and Saturday from 8 a.m. to 3 p.m., with Sundays closed; that Saturday window helps if you cannot spare a workday. The shop also mentions a free courtesy shuttle, so ask how far it goes when you book. Describe the noise or vibration as precisely as you can: when it happens, at what speed, and whether pressing the brake changes it. Good notes shorten the inspection. Request a written estimate before work begins, as state rules require, and find out what warranty the parts and labour carry. If a catalytic converter needs replacing, California requires a CARB-approved unit for your vehicle, so confirm that is what is being quoted.
Area covered
Mission Boulevard runs north toward San Leandro and south through Union City into Fremont, while San Lorenzo and Castro Valley border Hayward to the northwest and north. That puts the shop within an easy drive of most of central Alameda County, and Newark and Dublin drivers can reach it by Interstate 880 or Interstate 580.

Services
Typical for this type of businessReplacing worn mufflers, rusted pipes, broken hangers and failed gaskets, the parts behind a louder exhaust note, a rattle under the car or the smell of fumes.
Pads, shoes, rotors, drums and calipers, plus a brake-fluid check, when stopping feels soft, the pedal pulses or the brakes squeal or grind.
Tracing leaks along the system from the manifold to the tailpipe, since a small crack can raise noise, trip a check-engine light and let exhaust gases reach the cabin.
Swapping a failed or stolen converter for a unit approved by the California Air Resources Board for the vehicle, which a smog inspection will look for.
A look at the brakes, exhaust and nearby suspension parts while the car is on the lift, noting wear so repairs can be planned before they become urgent.

Common questions
Typical for this type of businessHow can I tell my exhaust needs work?
A louder or deeper sound at idle, a rattle from under the car, a fuel-economy drop or an exhaust smell inside the cabin are the usual signs. Fumes in the cabin are a safety issue, so get the car looked at promptly.
How often should brakes be inspected?
Most makers suggest a check at every tire rotation or at least once a year. Squealing, grinding, a pulsing pedal or a car that pulls when braking means an inspection should not wait.
What does California require for a replacement catalytic converter?
A replacement must be approved by the California Air Resources Board for your specific vehicle, and the approval label is checked at smog inspections. Ask the shop to confirm the part number before installation.
Original-equipment or aftermarket exhaust and brake parts?
Aftermarket mufflers, pipes and brake pads are common and usually cost less; original-equipment parts match the factory fit and sound. Ask which is being quoted and the warranty that comes with each.
Before you hire
- Get a written estimate before authorising work, as the Bureau of Automotive Repair requires.
- Look up the shop's Bureau of Automotive Repair registration online before a first visit.
- Ask what warranty covers exhaust and brake parts and the labour to fit them.
- For a catalytic converter, confirm the replacement is CARB-approved for your vehicle.
- Ask how far the courtesy shuttle goes if you plan to leave the car.
