SOURCE: 2002 Toyota Sequoia power brake booster % master cylinder are bad

Mr. Clark:
It would be extraordinary for a technician to recommend a booster and a master cylinder with no previous mention from you of a possible problem in this area. In other words, the technician had no business looking at the m/cyl or the booster, unless you told him that your braking was deficient.
Here is what REALLY happened: Somewhere, I'd bet, your brake light came on, and somebody "topped off" the master cylinder, to shut the light off. Now, please understand that the brake fluid level in the master cylinder reservoir DROPS PROPORTIONALLY to the wear of the brake pads. When the tech replaced the front brake pads, he obviously had to squeeze the caliper pistons into the housings to allow the insertion of the new pads. This action forced the brake fluid from the now-compressed caliper pistons BACK into the master cylinder, and it sprayed out from under the cap, coating the cylinder and the booster. Tell that repair service that you do NOT need a booster and a master cylinder, THEY caused the problem with the fluid being everywhere. I am confident that I just saved you a significent amount of money that you do NOT need to spend. Have a great day.

SOURCE: 2008 Toyota Tacoma Excessive brake pedal

Your dealer is not lying to you.
All of the Toyota product line with ABS has this phenomenon. What Toyota has done is incorporate "Brake Force Distribution" into the braking system. What that means is there is now a sensor on the brake pedal/brake rod, going to the master cylinder. The sensor measures how FAST you press on the brake pedal. This activates the ABS pump, and supplies more brake fluid, harder, to reduce the time needed, such as a "panic stop"; the pedal travel is much longer than you are used to, because of the way they have to measure the speed of the rod being depressed. In actuality, this system is much better than the old system, as it also prevents wheel drag. It just takes a while to get used to. Really, there is nothing to worry about, I explain this same thing to my customers every week.

I hope this helps you out.

Thanks for choosing FixYa for assistance.

HI, i would advise to check the following areas for faults. replace any part that is fouled or malfunctioning.

1. Check the air filter- This device may be clogged or dirty. replace if visibly fouled.
2. Check the fuel pressure regulator- pull the vacuum hose of the regulator. if there is gas in it, replace the fuel pressure regulator.(if there is no fuel present in the lines, move on to the next check point)
3. Replace the fuel filter and, check the voltage at th fuel pump. you should get 12V at the pump. if its lower than twelve, chekc the ground for corrosion as well as the entire wiring harness as well. all the way to the relay for fualts.
4. Check the Intake Manifold Gasket for worn or damged edges. this ware and tare will cuase leakge. replace this gasket if found to be fouled in any way.
5. Check the freash air intake hose. this hose may be clogged or damaged.
6. Last but not least, check the injectors for leaking seals and, correct pulse as well. replace any injector with a weak pulse or , leaky seal.

When the brake is applied the engine quits on a 1999 toyota sienna


Does this vehicle have power brakes? If so, then check the vacuum booster for the brakes.

It sounds like when you hit the brakes, the vacuum booster is leaking, causing the engine to stall.

Do this by unhooking it, and plugging it off where it goes to the motor, so the motor port is sealed. Don't worry about where the line plugs into the booster for now. Then, try hitting the brakes with the motor running. The brakes will be much harder to push now, as you have disconnected its booster. If it no longer stalls, then you will know that your brake booster is bad, and needs replacing.

Unless you are machanically inlined, have a good garage replace the booster. Midas will do, since they are a brake place. Used to be they tested, or checked, your car for free. Maybe they still do, but don't let them sell you anything you really don't need.

I replaced the master cylinder and brake pads and my brakes still dont work on my 1998 chrysler sebring


Have you tested your brake booster and your calipers?Your brake booster doesn't make any noise, and it doesn't use any electricity or gasoline, but it ensures that you can stop your car with only a light touch of the brake pedal. Things weren't always like that: before the invention of the vacuum brake booster, cars still stopped. It's just that you had to really stomp on the brake pedal. The modern brake booster is an ingenious device that operates using something that your engine generates whenever it's running: vacuum. The brake booster takes engine vacuum via a rubber hose that runs from the intake manifold, and the brake booster uses that vacuum to amplify the pressure you put on the pedal. A light application of the brakes is translated by the brake booster into significantly more pressure on the brake master cylinder, ensuring that your car stops quickly. So what happens to the brake booster if your car stalls, resulting in a loss of engine vacuum? Early designers realized that gas engines were hardly foolproof, so they designed a little check valve into the brake booster circuit. The brake booster stores enough vacuum to provide full boost for two or three pedal applications even after the engine dies. The check valve on the brake booster is what keeps that vacuum from leaking out. And speaking of leaks, that's the reason most brake booster units have to be replaced. As your brake booster ages, the rubber seals and diaphragms that hold the vacuum tend to wear out and crack. If the brake booster can't hold vacuum (despite the check valve's best efforts), its time is up and you'll need a new or remanufactured new brake booster.
