Can you bleed two brakes at once?

Each of the wheels has its own dedicated brake line, therefore it’s OK to just bleed one brake caliper. (so long as the brake fluid doesn’t or hasn’t drained below the low level mark in the reservoir). This independent brake line layout is common to most cars and it’s OK to bleed just one caliper.

Why are my brakes still squishy after bleeding?

Do you bleed brakes with engine running?

Brakes are bled with the engine off. A running engine supplies vacuum boost to the brake system. To properly bleed all the air from the system, there needs to be NO boost. Just pump the brake pedal until a solid pedal is felt, then bleed each caliper (if equipped) until air is evacuated.

What causes a soft and spongy brake pedal?

Corrosion inside that wheel cylinder can cause brake fluid to leak resulting in a loss of hydraulic pressure. This leads to a low or soft/spongy brake pedal. If the vehicle has a rear brake drum/shoe and pumping the brake pedal improves the brake pedal, the rear shoes may be out of adjustment.
