Mushy Brake pedal & High Pitched Squeal

[sangeeth]

Good day to all! Newbie here and looking to fix a rather disturbing problem. 

Car is a 2013 Silverado; Everytime I hit the brakes a bit too hard there's a high pitched squeal that shoots out of the (I'm guessing) master cylinder area. The truck has 60,000 miles on the clock and only ever been serviced at the dealership. Took it in last week for a service and the said they need to replace the master cylinder and brake booster to fix the squealing noise. 

 

Just curious if this is a common problem on these trucks? Is there a solution other than outright replacement of the parts? I can work my way around a car so DIY isn't a problem. 

 

Thankyou for reading!

the squeal could come from the brake booster if it is leaking

Do you mean air or fluid leaks? As far as fluid is concerned, externally, there are no visible fluid leaks or any decrease in the brake fluid level either.

Do a Google search to see if there is a TSB or Bulletin which should describe the symptoms and how to repair. If it is a known problem something should pop up when you do your search. Good luck.
