Question about Lexus LX 470
Last night my engine hood latch gave away (had recent front end body work due to an accident). and the hood flew open while on the highway going about 65mph. Fortunately it wasn't. During rush hour being startled I did stomp on the breaks but do not recall if they had actually locked up or not. Once I had slowed and pulled to the shoulder the hood came back down. Besides a dented/bent hood and high blood pressure I was able to secure the hood in order to drive home. After driving about 5 minutes, started to lose brake pressure and then the ABS light and alarm came on but did make the last couple minutes home safely. My question is what the relationship if one is) to the hood incident and the brakes, aside from me slamming on the breaks which I do know could be a contributing factor. One other item is that the driver’s side hood hinge did separate from the bottom mounting, which is located next to the brake fluid container but there is no visible damage to the break system in that area the brake fluid is at the appropriate level. Just no brake pressure and the ABS light and alarm now constant. ......Master Cylinder??

i would check front and rear brakes if rears are drum brakes i would inspect springs and hardware making sure everthing is conected and in place also make sure they are adjusted properly in the front and if rear disc i would make sure to grease caliper slides these allow caliper to move and its important that all moving brake parts are free push caliper pistons in alittle to see if they are sized or not booster is ok and most of the time when master goes it will leak where it meets booster and you will have a low brake pedal or no brakes

It sounds like the rear calipers are bad. Raise the rear wheels and see if you can turn the tires. If you can't, open the bleeder. If you still can't replace the caliper. If you can turn the wheel after you open the bleeder, replace the brake hose to that wheel.

it sounds like you've got an issue with the engine vacume line going to the booster. there's an in line one way check valve that keeps vacume in the booster in case of a loss of vacume, like if your truck stalled while driving. but there should always be vacume with the engine running. so check the vacume line going to the brake booster for kinks obstructions, and leaks.

does the truck have rear drum brakes on the rear? if so then the fluid is leaking out of the rear wheel cylinders. or the master cylinder is leaking fluid into the brake booster.
