If your '91 to '95 Jeep Wrangler YJ has a hard brake pedal or you're losing assist, the brake booster might be shot.

Here's a brand new replacement from QEARL AUTO PARTS.
It's a vacuum power brake booster designed for the 2.5L and 4.0L models.
The manufacturer part number is 54-74075 (also interchanges with 5474075).
It has an 8.73-inch diaphragm.

Important: This is just the booster – the master cylinder is NOT included.
Also, it doesn't come with instructions, so professional installation is highly recommended unless you're a seasoned mechanic.

It's made of steel and comes with a 2-year warranty.
