Question about 2004 Acura TL

1 Answer

Front brakes engaged while driving

My 2003 acura TL will engage the front brakes without input from the brake pedal. Seems to be associated with the wobble in front wheels occuring at 60-65 mph. In my case, the VCA light was not on but the Maint light was. Can't accelerate or get past 40 because the brakes are on! Can imagine what this is doing to the rotor and pads. I turned off the VCA system and got home. Am heading to my mechanic to find if the VCA or the ABS may be forcing the brakes following the wheel wobble. Anyone solve this ghost braking issue?

The problem will be in the master cylinder compensating port blocked
disc brakes do not have return valves or residual line pressure like drum brakes
if at any time the heated brake fluid is not allowed to expand back into the reservoir it expands and pushes the disc brakes harder on
catch 22 situation
dragging pads generate heat , fluid expands and presses the pads on harder = more heat =more pressure
the rotors have to be running true ( no wobbles) wheel bearings have to be correctly adjusted or replaced and the calliper body has to move freely on the mounting pins to allow for self centering action
instead of the mechanic go to an accredited brake professional shop and have a proper diagnosis and quote done

Check for brake fluids and make sure all the brake fluid container is closed tightly. Also, you make have to bleed the brakes.

1. torque on the slide pins is about 25 to 30 ft lbs.
2. torque on caliper bracket to knuckle is 80 to 100 ft lbs
3. get the best pad you can get ,its an Acura . I recommend Bendix import quiet ceramic pads.
4. ceramic = less noise/dust less stopping power
metalics= better stopping power/noisey lots of dust

The 4x4 will not engage on my 2003 ford f150. could it the dash switch?


Does yours have Electronic Shift on the Fly (ESOF) Operation The electronic shift on the fly (ESOF) system is an electronic shift 4x4 system that allows the operator to choose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL. The transfer case is equipped with an electromagnetic clutch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch on the instrument panel is turned, the generic electronic module (GEM) recognizes that a shift has been requested and activates the electromagnetic clutch and the relays which power the transfer case shift motor. When the shift motor reaches the desired position, as determined by the contact plate position inputs to the GEM, power to the shift relays and motors will be removed. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.

After reading this material I would not think it was the switch . Maybe an input problem to the GEM module .

Feature Inputs:
  • 4WD Mode Switch (various resistances; go to Table 1).
  • Contact Plate Position Inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
  • Output Speed Shaft (OSS) Sensor (Sinusoid Signal: 0.7V-20V, 2.2 Hz/mph).
  • Brake Input (battery voltage when brake is depressed, open circuit when not activated).
  • Transmission Range Sensor (grounded when transmission is in NEUTRAL, open circuit otherwise).
  • Start/Clutch Depressed Input (go to Table 3).
  • I would take it and have it check for codes !

What would cause there to be no brakes what so ever even after replacing all the broken brake lines and bleeding them all on a 2003 Hyundai elantra?


if this has anti-lock brakes it may be the HCU(hydraulic control unit) may have air in it. it may have to be activated to get all the air out.

Why are front brakes staying engaed


1. The master cyl has a valve that maintains a small amount of pressure on the brake fluid to keep the caliper pads close to the rotor otherwise you would have to pump the pedal to get the brakes to work. If you think the front brakes are too tight.. try opening the bleed screw on the back of the caliper and see if there is any pressure there after this condition happens. or jack the truck up and try turning the tire/wheel. This will only work if the problem exists when you try it.

Before jacking the wheels off the ground, use an appropriate socket with a solid drive size (1/2 inch drive usually works) ratchet or drive handle, and bang it with a sizable rubber mallet to loosen the lugs. In extreme situations, penetrating oil or WD-40 can be applied and let set for a few minutes before trying...

How to fix cruise control


Cruise controls can cease to engage if the clutch or brake light cruise switch are out of adjustment. If this happens, try placing you foot under the clutch pedal (if equipped) and lift up on it (toward you) and hold it while engaging the cruise. If it now works, it will likely cut out when you remove your foot from under the pedal. Check the brake pedal in an identical fashion. Adjusting the switch at the pedals can often solve he problem. Some vehicles (Honda, Acura, Ford, to name a few) have a plastic insert that mounts in the pedal arm which presses against the switch. These can become brittle and fracture into pieces. My Acura has little pieces of blue plastic on the floorboard around the brake pedal one afternoon and I noticed the cruise didn't work. It was the pieces of the insert that had come to pieces preventing the cruise from coming on. I replaced the insert and no more problem with the cruise.

My shifter won't shift. It seems like it is locked. I press on the brake but the little knob on the shifter that you need to push in to engage the shifter won't budge.


I'm assuming you're talking about an automatic transmission. When you press on the brake pedal, you engage a switch under the pedal which turns your brake lights on, and also engages a solenoid in the shifter which allows you to shift the car out of Park.

That said, are your brake lights working? If your brake lights come on when you press the brake pedal, chances are the shifter solenoid/actuator is broken. If your brake lights DO NOT come on when you press the brake pedal, chances are you have a faulty brake light switch.

Regardless which part is to blame, these are pretty simple and inexpensive repairs.

Good luck, and if this helped, please rate my answer!
