ken m Posted May 28, 2021 Share Posted May 28, 2021 I changed the accumulator on my 89 Reatta recently. Brakes work great but now I will get an intermittent whistling coming from around the master cylinder. It doesn't happen all the time and it is more prevalent in warmer weather. It will happen when the car is running and after the engine is turned off. It didn't start until after the accumulator ball was replaced. Any information would be appreciated.

Ronnie Posted May 28, 2021 Share Posted May 28, 2021 Check the vacuum lines near the master cylinder. One of them could have a hole in it. 1 1 Link to comment Share on other sites More sharing options...
