RV and Motorhome Brake Repair in Chino, CA
Air and hydraulic brake service for motorhomes, in Chino since 1967.
A motorhome stops a lot of weight, and its brakes get very little rest. McBride's services and repairs air and hydraulic brake systems on motorhomes at our shop in Chino, from a routine inspection to calipers, rotors, air system components and lines. We look at the whole system, not just the pads, because on a coach the problem is often somewhere other than where the noise is. Family-owned in Chino since 1967.
Does my motorhome have air brakes or hydraulic brakes?
Most gas coaches, including Class A coaches on the Ford F-53 and Class C coaches on Ford and Chevrolet cutaways, use hydraulic brakes. Most diesel pushers use air brakes. If you hear a hiss when you set the parking brake and you have an air pressure gauge on the dash, you have air. The full explanation of how the two systems work, and why each suits the coaches it is fitted to, is in our air vs hydraulic brakes guide.
What does an RV brake service include?
It depends on the system, and we recommend each service every two years.
Air brake service: replacing the air dryer filter, cleaning and inspecting the brake components, verifying the wheel seals, and assessing the tires.
Hydraulic brake service: complete caliper servicing, inspection of rotors and pads, a brake fluid flush, and an inspection of every brake hose and seal.
Both include a full system inspection, a check of the parking brake, and a test before the coach goes back to you. Brake inspections are also part of the major service packages on our RV chassis service page.

What are the warning signs of RV brake trouble?
On a hydraulic system:
- A soft or sinking pedal, which usually means air or moisture in the fluid, or a leak.
- Pulling to one side when you brake, often a sticking caliper.
- Grinding, or a pulsing pedal, which points at worn pads or rotors that are no longer true.
On an air system:
- Air pressure that is slow to build, or a low-air warning that comes on more often than it should.
- Pressure that drops overnight, a leak somewhere in the system.
- A parking brake that is slow to release, or a coach that drags.
On either: a burning smell after a long downgrade, or brakes that feel weaker the longer you use them. That last one has a name, and it matters here.

Why do my brakes fade coming down the Cajon Pass?
Coming south on the 15, the descent from the Cajon summit toward Devore is long and steady, and a loaded motorhome that rides its service brakes the whole way builds a lot of heat. Hot brakes lose grip. On hydraulic systems, old brake fluid makes it worse. Brake fluid absorbs moisture from the air over time, and moisture lowers the temperature at which the fluid boils. Boiled fluid means a pedal that goes soft at exactly the wrong moment.
What prevents it: fluid that is flushed on schedule, pads and rotors in good condition, and using a lower gear, an exhaust brake or a transmission retarder where the coach has one, so the service brakes are not doing all the work. If your coach has started to fade on grades it used to handle, bring it in before the next trip.
Does sitting in storage hurt RV brakes?
Yes, more than most owners expect. On a hydraulic coach, rotors rust, caliper slides seize, and the fluid keeps taking on moisture whether the coach moves or not. On an air coach, water collects in the tanks and the dryer works harder when the coach finally runs. A coach that sat through a season and now pulls, squeals or drags is very often telling you about storage, not about wear. Diesel pushers get the full air-system picture on our diesel motorhome service page.
Frequently asked questions about RV brake repair
Do you work on travel trailer and fifth wheel brakes?
We service running gear on towables, including axles, bearings and wheels, and hydraulic brake systems. Most travel trailers use electric brakes, so tell us your setup when you call and we will confirm before you bring it in. See our travel trailer repair page for the rest of the towable work we do.
Can you check the brakes on the car I tow?
The hitch, wiring and towing setup are covered on our RV tow package page. Call and tell us what you are towing.
How do your estimates work?
We inspect first and quote second. Estimates include a budgeted amount for parts, and the final price adjusts to the parts actually used.
How long does a brake job take?
It depends on the system and on parts. We give you a real drop-off and pickup date when the coach is booked, and we tell you if a part changes that.
Do you offer mobile brake service?
No. McBride's is in-shop only, at 13788 Oaks Ave in Chino. Brake work on a coach needs it supported properly on a shop floor.
When are you open?
Monday through Friday, 8 AM to 4 PM.
Bring the coach in and we will inspect the whole system before we quote anything. McBride's RV has been family-owned in Chino since 1967. Call (909) 627-7566 to book brake service.
