SOURCE: 1996 T-100 dash brake light will not go out

The brake fluid level sensor in the master cylinder is stuck in the lower position which completes the circuit to illuminate the light.. Try tapping lightly on the side of the reservoir to loosen it. If that does not help, you will need to replace the level sensor.
Thanks for choosing FixYa for assistance.

SOURCE: cant bleed out brakes

It takes time, do you know the sequence to bleed the brakes? Most cars r different. And you have to keep pouring brake fluid, That is a two person job. Make sure all lines r connected to MC and not leaking. After a while if nothing comes out MC could be diffective.

SOURCE: 1993 toyota corrolla brake problem My right side

The only other valve that would hold residual pressure is possibly the proportion valve if so equiped. If you follow the brake lines from the master cyl, they will lead yo to a muti port valvethat has all the brake lines on it. Look at the ends of the valve and tell me if there is a pin protruding from one or both ends. If a pin is proyrudingfrom one end and not the other I'll tell you how to fix it.

SOURCE: How do I bleed master cylinder for 90 Toyota

You will have to bleed the whole system, front and back, start with the right rear, get somebody to pump the pedal, put a hose on the lock nut, catch the oil in a can, pump up the pedal, it won't get hard till a few times doing this, crack the bleeder, tighten it back up before the pedal is released, pump again, crack,tighten, pump, repeat, go all the way around the car, keep checking the reservoir, it will pump up soon enough. You might have to go around 2 or 3 times, Now,,,, the part about the pedal going to the floor and getting hard after car is shut off, sound like you didn't hook up the vacuum line to the booster. It has an atmospheric thing going on there. Check the big hose going into the booster, which is that big round thing behind the fluid reservoir. Hope this helps.

1993 4wd. Why aren't brakes working?


Does the brake pedal go to the floor? Or does it stay up, and is hard to push...? Did you bleed the master cylinder? Also, you will need to bleed all 4 wheels connection to the brake wheel cylinders...you must start with the rear, farthest from the master cylinder, then other rear, then front farthest from the master cylinder, then other front...the bleeding of each line is a must, since you switched the master cylinder.

Take Off Nuts That Hold Master Cylinder To Booster. Pull Master Cylinder Away From Booster--Do Not Damage Lines--Feel With Finger At Rear Of Master Cylinder For Fluid--If Found Replace Master Cylinder And Booster With Total Unit Combo For Better Warranty. DO NOT FOOT BLEED--Pressure Bleed Or Gravity Bleed Only.

Have a 99 Toyota camry n brake light is on after changing right front brake caliper


Master cylinder fluid piston has entered into a brake safe mode.
when the high pressure brake system is opened in any way, the brake master cylinder piston reaches to the far end of the master cylinder which trips the brake system warning light.

This brake light condition is due to sudden loss of brake fluid pressure on the right front brake caliper assembly during the replacement.

Left rear brake caliper bleed valve will ned to be "opened" until master cylinder piston travels into the opposite direction which "resets" the brake system warning light.

Dot 4 brake fluid recommened for most, but not all vehicles.
Reference vehicle to owners manual for replacement fluid is replaced under master cylinder brake system cap.

Air in the fluid master cylinder


Do you mean the brake master cylinder? As long as the fluid is at the full mark, and you have no air in the brake lines, it is fine. A spongy brake pedal and poor braking operation happens when air is in the lines. Air can get into the lines when the fluid in the master cylinder is very low, almost out, or when a brake line is pulled apart (like when replacing calipers). To get the air out, one has to bleed the brakes-starting at the rear tires-the longest run from the master cylinder-and ending at the driver's wheel -nearest the master cylinder. Opening the bleed valve at each wheel in turn and pumping the brakes will force fluid into the lines and push the air out the bleed valve. When done properly, all the air in the brake lines should be expelled, and the brake pedal returns to it's firm pedal and good braking efficiency.

I just replaced the brake master cylinder and rear wheel cylinder on my 1987 toyota pickup, and now I have no fluid going to the back brakes. Bleeding them does nothing


check for fluid before and after the proportioning valve by disconnection the line after the valve and applying the brakes, if no fluid after valve try before valve if fluid is there then it is a bad proportioning valve. you did bleed the master cylinder before connecting the brake line and trying to bleed the brakes all at once right? If the master cylinder was not bled first then a lot of air may have been forced into the rest of the brake lines.

Brake problem hard to press on 1995 toyota 4 runner. replaced calipers and pads rotors and bleed the lines three times. Is it the master cylinder or power booster


When you expeirience a hard brke pedal the first thing to diagnose is a bad or inop power brake booster. First thing to check is the vacume check valve on the booster housing that is connected to a vacmue hose. Be sure you do have vacume from the hose first before replacing check valve.
