Toyota Land Cruiser HJZ75 brake problems
I have a problem with all four wheels brakes binding at the same time. What could cause that ? Happening to two vehicles.

The Toyota Land Cruiser got a significant redesign for 1998. Most notably, the V6 engine was swapped for a much beefier V8. The suspension was improved, the towing capacity was increased, and the body made larger. The appearance didn't change much; the 1998 Land Cruiser kept the familiar boxy shape. But the interior was updated, mimicking that of the 4Runner.
The 1998 Toyota Land Cruiser came in one, well-equipped trim level. The new engine was a 4.7-liter 230 horsepower V8. The only available transmission was a four-speed automatic, and the four-wheel-drive was permanently engaged. The '98 Land Cruiser seated five, but with the optional third row could seat up to eight. Fuel economy was about 14/16 mpg.
Land Cruiser fans were pleased with the SUV's additional power. Those who drive the 1998 Land Cruiser have little to complain about, citing the generous amount of cargo space and towing capacity, luxurious interior, and excellent handling as reasons why they love the Land Cruiser. Some do complain about the expense of purchasing and filling up the 1998 Land Cruiser, but most say its good points more than make up for it.
