Re: Different brake pedal feel after booster replace

I like to change the brake fluid & coolant every 2 years. I also change the thermostats every couple of years to minimize the risk of them failing closed, failing open, or hanging somewhere in the middle. If fluids haven't been done in a while then more frequent changes should be considered because the new fluid will start cleaning things up.

For brake fluid, if you have that plastic reservoir and its got a lot of residue in it, the new fluid will start cleaning it up and leaving it in suspension. If the reservoir isn't cleaned or replaced this can go on for quite a while. The old metal GM style ones were a lot easier to clean.
