Disc Brake Pad Wear Warning Indicators; Brake System - Subaru 1998 Legacy Owner's Manual

J Brake system
B Two separate circuits
Your vehicle has two separate circuit brake systems. Each circuit
works diagonally across the vehicle. If one circuit of the brake system
should fail, the other half of the system still works. If one circuit fails,
the brake pedal will goes down much closer to the floor than usual
and you need to press it down much harder. And a much longer dis-
tance will be needed to stop the vehicle.
B Brake booster
The brake booster uses engine manifold vacuum to assist braking
force. Do not turn off the engine while driving because that will turn off
the brake booster, resulting in poor braking power.
The brakes will continue to work even when the brake booster com-
pletely stops functioning. If this happens, however, you will have to
push the pedal much harder than normal and the braking distance
will increase.
J Disc brake pad wear warning indicators
The disc brake pad wear warning indicators on the disc brakes give a
warning noise when the brake pads are worn.
If a squeaking or scraping noise is heard from the disc brakes while
braking, immediately have your vehicle checked by your SUBARU deal-
er.
