SOURCE: 94 4runner brake pressure.

did you possibly replace brake lines with standard instead of metric lines.The standard lines will fit but you will not get pressure back

SOURCE: no brake line pressure on 1 caliper after replacing caliper

I suspect you may have twisted the hose on re assembly. The other possibility is that the bleed nipple is choked with dirt and rust. Remove it completely and see if the fluid starts to run out. If so replace nipple or clean out.

Cheers John

SOURCE: brake pedal dropping to floor

do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.

I had a similar issue when i replaced the brakes on mine. Turned out that I had a bad caliper. Onc e i replaced that, it was fine. Also, when the car is not running, your brakes will "pump up" because the master cyl. is not operating

Why do my brakes pump up after bleeding and still go to the floor when i start the truck?


Hello.

If the brakes pump up after you start your engine, it means your brakes are good and there are no bleeds.

They pump up as the car builds pressure inside the brake fluid circuit.

If the pedal loses pressure and hits the floor while the engine is on, this means that you may have brake fluid leaks and your brakes won t hold much longer (needs immediate fix).

Starts then dies & won't restart


check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

There is no pressure when i press down my clutch, I just had it replaced about a year and a half ago. It didn't feel like the clutch went?


clutch master or slave cyl. could have gone out so you are no longer releasing clutch thats why no pressure on pedal. look for Brake fluid leak -clutch uses same type of fluid. or master cyl can leak or bypass internally and just not build pressure.

When engine is running and you press brake pedal it will have pressure the tavel to the floor. but when you turn off engine pedal is hard.


sounds normal.... when the engine's running, there's power assisting you as you brake to move all that hydraulic fluid from the master cylinder to each of your wheels... when the car's off, there's no power assist as you press on the pedal causing it to feel hard as you have to use your own strength to push on the pedal. also with the car off, the fluid pressure just keeps in the line and is not returning to the master cylinder, causing that pedal to feel harder with every press

2005 Chevy trailblazer is leaking power steering fluid


What the seal leaks do is soften the rubber, not the best long term solution. Try taking a wrench, the correct size, and snug down all the fittings, not to tight. If it is coming from, as you described, down through the boot it could be a seal. Wipe down the unit well and watch as you have someone tune the wheel back and forth. The engine should be running to build up pressure, so be very careful not to get run over. Apply the emergency brake well and chock the tires.
