Passat (B5) :: Inefficient Braking Action Especially In Reverse


Aug 4, 2008

Here's an interesting problem our B5 (2001 1.8T) has experienced recently -- When backing up and then applying the brakes there's very little effective braking occurring, sometimes to the point of the pedal traveling almost to the floor. I've recently had the brake pads and rotors checked -- all rotors are OK and the front pads are "almost new" condition. The rear pads were showing significant wear and I had those replaced, but we're still seeing the same problem.

I can also tell that braking action driving forward feels less than optimal, although not nearly as troubling as when attempting to stop in reverse. I'm suspicious of a problem with the vacuum assist unit, either a bad hose or possibly a defect in the boost unit itself. Can the VW shop definitively test the appropriate vacuum line(s) to the booster and the booster unit itself for a problem?

SC/SL/SW :: 2001 SL1 Saturn Will Not Go Into Gear After Hard Braking Action

Sons saturn will not go into gear after a hard braking action. The shifter will move, the car just acts like it is in nuetral, engine revs with gas, no movement in any gear or reverse. After waiting for a few minutes he can put it in gear and go as if nothing happened. I have checked the fluid, its nice pink and clear and full. He says it has happened 3 times in the past week, has driven it for over a year with no major problems. He is 17, but seems decent with a manual.

I have tried to replicate but can not the car drive good, no shifting problems on normal driving and no check engine lights.

Toyota - Camry :: 2003 - Pedal Will Travel Excessive Distance Before Any Braking Action

I own a 2003 Toyota Camry SE four cylinder sedan with only 46,000 miles. The car has four wheel disc brakes and an anti-skid braking system. About a year ago, I started to notice that there was excessive travel in the brake pedal. That is, the pedal will travel an excessive distance before there is any braking action. I have tried to correct the problem by pumping the brakes as I back out of my driveway to engage the self-adjusting mechanism; doesn't work. I have also gotten in the habit now of pumping the brake pedal; that works a little, but it's not a solution. Being an old chap who always maintained my car myself, and diagnosed and repaired most problems, I concluded that the problem was the master cylinder because when stopped at a light, the brake pedal would continue to go down. Incidentally, there has been no loss of brake fluid since I bought the car new in 2003. Recently, I had the master cylinder replaced and learned that I'm not as car-smart as I thought. There is no improvement in the pedal travel problem.

Golf IV / Jetta IV :: Engine Misfired Twice And CEL Came On For Code P0420 / Inefficient Catalyst

I bought my Jetta almost a year ago, and I've been constantly replacing parts. Unfortunately, my engine misfired twice and the CEL has come on for P0420 which is inefficient catalyst. This is the only code being thrown. I've cleared it like 10 times, but it keeps popping up.

Prius (Gen 3) :: ICE Action With No AC Or Fan On

The engine is fairly hot after driving 2 miles in hot weather. Waiting a minute or longer for green light. No A/C or fan. Battery is 3/4 full (judging by number of bars). Windows fully open to cool the cabin. My foot is on the brake. The ICE suddenly starts and turns off at the same time. I had the car for near 3 years and this is the first time.

Touareg :: Clunk When Braking In Reverse?

So I noticed my Treg makes a clunk when I break when backing up. If I hit the gas, then brake, 'clunk'. Sounds like its coming from the rear or undercarriage. Hopefully not serious but its going in for service soon.

Prius (Gen 3) :: Overly Sensitive Braking When In Reverse

I've noticed over the last year or so that when I put my car in reverse to back out of a parking space, occasionally, the break pedal will not fully depress - probably goes about halfway down - and the braking becomes very sensitive. I cannot smoothly back out because the brakes keep catching. Once I've switched back to forward drive, the problem is resolved. Is this normal, something I'm doing wrong, or does it indicate a braking problem that needs to be fixed?

Touareg :: Single Clunk When Braking While In Reverse

I get an audible 'clunk' whenever I brake while in reverse. The sound reminds me of my old 4X4 when I would back up to take it out of 4 wheel drive. I searched for some existing posts but didn't get the keywords right or they don't exist.

Celica :: 1989 - No A/C Condenser Fan Action?

Wife found and purchased a 1989 Celica GT...everything is mechanically sound...except that when we took the car into service place to get a/c service done, they charged the system and said that it is fine...(was a few ounces low on freon), but that our condenser fan doesn't seem to kick on when the a/c button is activated on the dash We have the "Push Button" style Automatic a/c. Manual trans, 3sfe 2.0 liter. I have checked voltage at the condenser fan...it is present....jumpered the ground wire to a ground and the fan runs...I swapped the relay out with the regular engine fan relay, which seems to work fine....no good, so I don't think it is a relay issue.

The compressor seems to kick in and work, cycling on and off as usual. Get nice cold air as long as car is moving above 30 mph. I have the tools, no real fear of taking stuff apart, but even though I have a schematic of the a/c system...I find it confusing and daunting. My service place mentioned either the a/c controller or the a/c amplifier may be the culprit. He also mentioned that those parts are no longer available from Toyota.....said there was a way around it to get the condenser fan to fire when the button is pushed on....but wanted $300 for the "no more than 30 minutes to do the wiring". He seemed rather "sharkish" to me....like instead of charging for time, he put a "what's it worth to you to have a/c" hijack price on it.

Dodge - Grandcaravan :: Clunking Noise When Braking In Reverse

If I am moving in reverse and tap the brake I hear a clunk from the rear of the car. If I continue in reverse and then again apply the brake then no clunk. If I drive forward and stop, no clunk. If I then shift into reverse again and apply brake I get the clunk again. Had the struts/shocks replaced but no change.

Accent RB (2012+) :: Noise Whenever GDI Pump Is In Action

I have a 2014 Accent (standard) and I have been noticing a noise when ever the GDI pump is in action. Noise was much louder in winter as if a hard plastic piece was transmitting vibration, this is very annoying. Dealer's technician confirms its from GDI but tells me its normal, I do not remember earing that noise in the car I test drove before buying. This is the only downside to my new car but a big one for me.

Grand Prix :: 2004 - Loud Clunk While Having The Car In Reverse And Power Braking It

In my 2004 Comp G I have an extremely loud clunk when braking. The braking clunk does not happen all the time. There is a clunk while having the car in reverse and power braking it. While holding down the brake and revving hard and fast it make the loud clunk every time. It will not do it all the time in drive though. I can not pin point which side it is coming from. It sounds as if it is mostly the right. It almost sounds as if it is coming from inside the trans near the pan area?

I have replaced the lower control arms, sway bar bushings, stab links, struts & mounts, I have solid engine and trans and top mounts, new inner and outer tie rods, all wheel bearings, etc.... (not for this issue, just for performance/wear).

I am torn between thinking it is a cv axle or internal drive train noise.

Gti - Volkswagen :: 2001 - Shift Action Feels Longer And Sloppier

I have a 2010 VW GT with the 6 speed manuaI. The shift action feels longer and sloppier than the action was on the five speed from my much missed 2002 VW Passat wagon (only option the v6 engine). I'm considering a short throw shifter and would like to understand the pros and cons, and which shifter would be the best one for my car.

TrailBlazer :: Grinding Noise Coming From Front Left Wheel When Braking In Reverse

So whenever I brake while reversing (and rarely while moving forwards) I hear this odd grinding noise coming from the front left wheel and can feel it through the brake. Im not a petrol head but I decided to replace a wheel bearing hub myself recently to save money. I am pretty sure I reconnected the anti lock brakes correctly though I doubt it's that. My brakes are good.

Accent LC (2000-05) :: GS Will Not Start - No Instrument Panel Gauge Action On Crank

I have a 2002 Accent GS. Their is fuel flow out of the fuel filter. I've changed out the spark plugs and sprayed starting fluid into the cylinders, and still will not start. So there is no electricity to the spark plugs. Replaced all of the ECU fuses in the engine compartment and under the dash, and still will not start.

Don't think it is the coil pack, because I can't imagine both coils failing at same time. Think it is a relay or sensor. Which relay or sensor would also prevent power from going to the instrument panel gauges but still allow the instrument panel warning lights? Main relay? Crankshaft position sensor? Throttle position sensor?

Ford - Explorer :: Violent Jerking Action When Hitting A Bump In The Road

I have noticed a serious bump steer or a violent jerking action when hitting a bump in the road. Just over a year ago I replaced ball joints,tie rods, sway bar links (2nd set since cutting off original). I used MOOG components. I was shocked to see the sway bar links loose once again. Is there a certain way to tighten them or is there a better product available. Mostly stock 1999 'ploder with fire wires and scremin demon coil pack.
