Question about Lexus LX 470

Open Question

Lexux 1999 lx 470 no brake pressure and ABS light

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.

Brakes are hard to depress causing stopping problem

1: inspect all brake linings first.
no pulling left or right braking?
the car has 100% full manual brakes. if the brake booster fails.
(its only and assist !!! for 50lb small folks)
so does it? it takes more pedal pressure but has 100% full braking.
this is no accident its by design.
make sure none of the brake shoes/pads are soaked in DoT3/4 fluid
or grease or gear oil.
and no brake fluid leaks end to end, this is really #1 on all cars.
look, then look again. even behind and in front of the master cylinder.
look at tires (inside for fluid leaks>)
2: do the booster test. did the vacuum hose to it fall off?
or got pinched, or ?

google brake booster test
if ABS system. get it all checked,
if ABS get the ABS scanned.

if you cant stop correctly,,,,???? , dont drive.
get it fixed.

(1999 Ford Windstar) Not only does my front end shake when I brake hard, but I had a situation the other night where the brakes did not hold. It was a bit rainy that night. As I approached an...

reason the front end shakes is the rotors are warped. when you do go to the garage makes sure your not turning the rotors past there minimum thickness. have him check the rear brakes as well for a clean and adjust (rear drum brakes) or for there condition as well. should be a normal front brake service

Abs light on and trac off light on new front brakes recently installed

First thing I would check if brakes were installed is that the abs wires did not accidentally get disconnected. If that did not occur you will need a scan tool to determine why the abs light came on. It is probably due to a bad wheel speed sensor.The trac light is on because currently your abs is disabled and the traction control requires use of the abs system to function.

I'm after changing my front brake pad on my 03 audi a4 afterward speedometer isn't working and engine check light abs esp light are all on

The speedo not working causes these 3 lights to come on due to the speed of the car needed for the ABS ESP to work . Engine management light is on due to the first 2 lights . Happenned to me last night. Dont know what is up with your speedo . You have to reset the lights after speedo fixing as I am uncertain whether they will reset themselves.

ABS light constantly on

Possible that a ABS rotor was damaged when the work was done or the sensor is not close enough to the rotor or wheel bearings are packing up
