BRPOWER BRAKE PROBLEM

1998 Toyota 4Runner • 4WD Automatic •

'98 4 runner: delay in power brake boost application. Frequently hard to press until brakes begin to work, then all is OK. This occurs about 50% of the time. Will always occur when car is first started. Check valve appears to be OK.

Little over 100k mikes. Disks and rotors are not very. Old 5 to 7,000 m. Brake fluid is not low.

This problem suddenly appeared.

Thanks

You may have a bad booster but it would have to be looked into deeper to conclude that.
