Did the dealership mess up my brakes?

2009 Prius with 129K

I had my brakes “flushed” by a Toyota dealership

A few days after the flush I started to hear the noise caused by the brake actuator pump ALOT more often. Like every other time I use the brakes in some cases.

Here are my questions:

1) Is this because I was on a long road trip in hot summer heat?

2) Is it possible the dealership messed up the break flush and damaged the solonoid valves?

3) Is it normal to hear the brake actuator pump after basically every other time I depress the brakes?


No lights are on, and it doesn’t feel like I have lost any pressure in the brakes.


The car is at 128,000 miles so warranty is out of the question but I might take it back to the dealership and discuss the possibility his technician messed up the car. They told me they have only done a brake flush on a prius “3 or 4 times” and it took them 6 hours.


They recommended I get the flush when they inspected the car for me before I bought it.
