Temperature affect brakes?

- Wed Aug 25, 2010 2:29 pm #210501 Yesterday my brakes felt like there was no pressure when coming to a stop. It would slowly and gradually sink to the floor. I would have to let go and pump the brakes a little to get brake pressure again. I took it to a nearby shop and they told me it's most likely the master cylinder going out. This morning on my way to work, the brakes felt normal. I live in a city that's usually 55 degrees year-round, but yesterday was almost 90 degrees Fahrenheit. My car was parked outside over night so the whole car itself was cold, now my question is, is it possible for the temperature in the weather affect my brake system? I recently did a brake job: oem blank replacement rotors, hawk pads, and goodridge stainless steel lines. All installed by a reputable shop.

That is why it is important to stick with the same brand and use the same brake fluid grade.
