2002 Toyota Sequoia power brake booster % master cylinder are bad

I took my wifes 2002 Toyota Sequoia SR5 4x2 in for oil change, tune up and to inpect the brakes. They changed the oil and filter, replaced the front brake pads and are telling me that my power brake booster and my master Cylinder are need to be replaced. When I questioned why both, I was told that the master cylinder leaked on the power booster or vice versa, thzats why they are both out.

This seems a little odd to me that noth would be out at the same time. At least my understandin is that the master cylinder goes out over time, and I didn't think it leaked, maybe the brake fluid. Please advise, I will get another opinion as well today.

Also do you know if the power brake booster and the master cylinder are the same on the 2002 Sequoia and the 2005 Sequoia?

Thanks

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.

Amen to that answer. tech that get paid by the job have a tendency to this **** not all tech just the ********. if your master was bad your brakes would be spongy and if your booster was bad your brakes would be verry hard

How to tell is the brake booster is bad in a 1986 dodge D100


This is a standard Vacuum operated brake booster.. If you are having fluid leaking at the rod that attaches the brake pedal to the booster it is a bad Master Cylinder. The Brake fluid will eventually destroy the diaphram in the booster if it hasn't already. . Replace or rebuild the Master Cylinder and wash the brake fluid out of the booster. When the booster goes bad the brake pedal will become very hard to push.. because you will have lost "boost" This is not really a hard job. If fluid id leaking somewhere else.it should be very easy to spot.. Brake fluid looks like oil leaking..

Bleeding 02 toyota sequoia


You have a helper pushing on the brake pedal when you open the bleeders? Is fluid coming out of the bleeders when you open them?

typically you will start at the right rear, then left rear, then right front, then left front. or work your way from the farthest bleeder to the nearest bleeder to the master cylinder. Make sure the reservoir does not go dry or you will have to start over.

It is possible that when you pushed the pedal to the floor the seals in the master when through some debris and where ruined.

Power booster seems to leak how to fix


These are not rebuild-able, they must be replaced if they leak.
One that leaks will hiss while the engine is running. The hiss is vacuum leaking, not pressure leaking out.
To possibly check it under the hood, be very suspicious of a leaking vacuum line at or near the booster, not the booster itself. It might be bad, but that is pretty rare.
The last one I changed I thought was defective because it hissed when I applied the brakes, but a new one did the same thing! :-(
If you decide to replace it, you will be unbolting the master cylinder from the unit under the hood, and also unbolting the unit under the dashboard.
Of you are really careful, you might not need to disconnect the master cylinder 's brake lines at all, just gently pull/push it out of the way to change the booster.
Be really careful not to kink the brake lines.
The unit is bolted to the car with usually 2 bolts through the firewall behind the brake pedal.

New rotors and calibers, with pads replaced and now every three to four days must add brake fluid and brakes work fine no sponge feeling.


Check for leaks around brake calipers or cylinders, check for leaks around brake master cylinder, may be leaking from master cylinder into brake booster, remove vacume line from booster and see if you can detect oil inside, if your adding oil to brakes every three to four days a leak should be easy to find.

1990 toyota pickup, idle is rough, just had oil change and major tune up


I would check for a cracked vacuum hose. This will kill a cylinder at idle. Also bad brake booster will cause this.

Sounds like she has a bad power brake booster/master cylinder. The master cylinder is leaking fluid into the brake booster which is sucked into the intake and burned which causes the smoke. Put a new booster and master cylinder on, and problem will be fixed.
