May 16, 2016

i have a 2010 Prius II that had a recall in 2013 on the brake boosted. I had a new booster pump put on and now three years later it has brake fade again. I am told from the dealer that it will cost 1800 to repair. So how long does a recall last.

Lexus RX 2010-15 :: Buzzing From Brake Booster Check Valve When Lightly Braking

The annoying buzzing from the brake booster check valve that comes from the left of the instrument panel when lighly braking (especially when parked or waiting at a traffic light) is a well-known problem, as it was the subject of a Lexus (and Toyota) TSB for 2004-2010 models(see link below to the clublexus link), and has been discussed on many forums for Lexus and other cars.

I just bought a new 2012 RX 350 last month, and within a week it started making this buzzing noise (left instrument panel upon light braking). I took the car to the dealer and without listening they said that they knew it was the brake booster valve (the noise is the rattling of a ball bearing when the valve is malfunctioning). They replaced the valve and the noise went away (the loaner RX they gave me made the noise even worse).

Well, 3 weeks later, the noise has returned!

Prius (2010-12) :: Brake Pump Dims Interior Lights When Open Driver Door

When I open the driver door at night, the brake pump would dim the interior lights a little while running. Is this normal for a 6 month-old aux battery? All my trips are 30 mins or longer so it has plenty of opportunity to recharge.

Volvo :: 1993 - Loss Of Brake Booster And Brake Lights On 940 Wagon

My wife was driving my 93 Volvo 940 wagon yesterday, and the brakes suddenly lost power, and brake lights went out. I have heard no hissing from the booster, and I have checked the 10 amp fuse on the relay beneath the instrument panel. Hoping (and praying) it is just one of the relays. I have a meter, but not sure which pins to use to check the relays. Secondary issue: the used radiator I bought did not have the cooling fan sensor, so I have my fan on a toggle inside.

When my wife pulled over because of the brakes, she did not turn the fan on. Yup. Overheated. Now the radiator leaks from the rubber/plastic plug where the sensor goes. Any pliable sealants that could withstand the temps? Cash is in very short supply right now. That is my main issue right now, trying to drive with no brake lights. No ABS light, and no brake light coming on on the dash. Bulbs are good. ABS light does not come on at all with ignition, but bulb tests good. Just hard brakes, and no brake lights.

Ford Excursion :: 2001 - Front Brake Sticking - No Power Assist - A/C Stays On Defrost - Brake Booster?

I have a 2001 ex. 4x4 6.8 v10. I have been having vacuum issues and brake issues lately. My front brakes seem to be sticking, some times they drag some times the don't squeeze when I step on the brake causing uneven wear and pulling when I stop. Also feels like I have no power assist. I also have a vacuum issue with the auto setting on the hubs, they don't engage I have to manually lock them and sometimes my a/c stays on defrost. And my cruise control doesn't work, the light comes on and love done the self check but it doesn't show anything is wrong. Could I have a bad brake booster?

Golf IV / Jetta IV :: How To Remove Brake Booster

How do you remove the brake booster rod from the brake pedal? The damn rod won't separate from that plastic housing. I've tried wedging a flathead in there but it's hard to see. I've been fighting with it all evening and finally gave up before I end up breaking it.

Found a DIY that just cut the rod to pull the brake pedal to remove it. I rather not do that as I will be reusing the one I have.

Ford F-150 - 1997-2003 :: Brake Booster Going Bad?

My 97 F-150 (4.6 L) has developed what sounds like a vacuum leak under the driver's side dash somewhere above the pedals. I can't see anything obvious. It changes sound with various positions of the brake pedal, and I can make it stop with hard acceleration for a few seconds. The brake pedal feels the same. I'm assuming the problem is probably my brake booster, right? Or should I be looking elsewhere? If so, how hard is it to replace?

Ford F-150 - 1997-2003 :: 2002 - Brake Pedal Fade / Started Going To Floor When Stopped

Last week my brake pedal started going to the floor when I stopped, it still stopped and felt fine on the top half of the pedal travel but then it would just slowly fade to the floor. I took it to a local shop and they said the master cylinder was leaking internally and my rear brakes were shot. I have 75,000 miles and the rear brakes were original so I told them to fix it. This is basically what I expected it to be.

They kept thinking they were getting defective master cylinders but after the two Napa parts and two Carquest parts they realized they misdiagnosed it and said I needed to take it to the dealership. I paid for the rear brake job since it needed done anyways and have an appointment for next week at the dealership. What might be causing the problem? I see no brake fluid leaks, no vacuum leaks, the booster was replaced 25,000 miles ago due to noise, no ABS light on, no CEL on, no other symptoms.

Chevrolet - S-10 :: 1996 - Brake Booster Vacuum Leak

Brake pedal whistles and is hard to push. Only happens intermittently. Mechanic wants to put new brake booster on. This would be 3rd brake booster in 9mos. It's gotta be something else. What does the vacuum hose connect to from the check valve; where on the intake manifold? If no PVC valve...then what else? Truck runs fine...no fast idle or rough idle and no hesitation.

Golf IV / Jetta IV :: Vacuum Leak From Brake Booster?

I need replacement vacuum hose part for my GTI 337. The piece that is disconnected is the hose from the break booster to the intake manifold. It appears to be at a one way valve. I found a picture from a different DIY, that I have circled in green. The red arrow points to the place where it separated. I am not sure if this is a matter of me using a new clamp or buying a new piece of hose from advanced auto parts. The vacuum sets on ECS Tuning and it doesn't appear to be the correct set.

Toyota - Highlander :: 2007 - Power Brake Booster Broken?

The power brake booster on our 2007 Toyota Highlander is broken and needs to be replaced. We asked our mechanic whether there are any brake-related recalls for our Make/Model/Year, and he said 'no'. Is this just our particular bad luck, or have others experienced similar problems with this SUV? It was scary. My husband was driving on the highway and needed to make a sudden stop due to a traffic slowdown. The brakes didn't respond, and he needed to slam down the brakes several times to get the brakes to work. No warning, the brakes just suddenlt stopped working.

Prius (2004-09) :: A/C Fade Out And Turns All The Way Off

I have an '05 Prius. I always turn off my AC before powering the car off. I used a sunshade. I don't turn on the AC for about a minute after starting the car and and/or getting up to normal speed. (about 35-40).

The AC will power on more reliably if on MAX. It will start to blow cold and stay on for about 45 seconds. Then, it starts to fade out and turns all the way off. If I allow it to wind all the way down, I can't turn it back on for about 10 minutes or longer. If I turn it off manually when it first starts to fade, the AC will allow me to turn it back on and get more cold air. (The problem is, I'd have to turn the AC on and off every 20 seconds or so to maintain cold air, and I'm not sure that's good for the car or battery...but I've done it before on my way to a wedding...didn't wanna be soaking wet for photos...and the air blew cold the entire 20 minute ride.)
