1998 GS 400 Brake booster squeal

Recommended Posts

My 1998 GS 400 has a squeal when applying brakes . Been doing that for 3 years without any loss in brake function. What happens when booster fails? Will I be able to stop the car  but with more peddle pressure needed  or will brakes fail ?  I understand that brake master cylinder and booster are all one unit and replacement parts cost $2500 without labor . Getting used to the noise which is not noticeable when temperature is above 75 degrees. Real noisy in  Buffalo winters however.

I have the same issue and I believe it is the abs pump building pressure to spec.I'm guessing no abs fault codes.
