Question about 1994 Chrysler LeBaron

1 Answer

When I apply the brakes, especially at higher speeds, the back of the vehicle starts to rotate conterclockwise for a moment then shifts the other way finally settling into a somewhat normal state. I've had the front pads and rear shoes replaced along with both rear wheel cylinders with no change in this annoying and potenciall dangerous problem. Is there some sort of brake proportioning unit that needs to be adjusted or changed. The car does not have an antilock braking feature. Thanks. Vince Granaldi Beverly, NJ

Hi Vince,

Re:" I\'ve had the front pads and rear shoes replaced along with both rear wheel"

Did they bleed brake fluid completely when you did the job? The left rear brake is braking before the right weel one. Air in the brake lines can cause the problem.

Did the garage do a brake test to find out the breaking power on each single wheel? What is the result, is it rear, front brake or both?

Apart of that the part that they should have checked is the brake proportioning valve, that will probably need replacement. The job is not a minor repair, better having it done by a mechanic.

    Also on LeBaron, in this Chrysler the master cylinder piston operates directly on one front caliper and on one rear wheel cylinder at the opposite corner at the same time. I did not drive your car, so I cannot tell which brakes are seizing, but a defective master cylinder can easily cause a similar effect.

    errata: In my last comment, where I wrote at the same time, I meant on the same line.

    By the way the master cylinder in this car can also cause a similar problem.

    Check in order:

    Fluid
    Master Cylinder
    Proportioning valve (this fails rarely)

    Good luck.

On my 2007 explorer the brake engage when you put the car in drive and the rcs light comes on


Do you mean the RSC light ?
  • Roll stability control (RSC)/interactive vehicle dynamics (IVD)
  • Roll Stability Control (RSC)
    The roll stability control (RSC) system monitors the roll-rate sensor and existing stability assist sensors and calculates if the vehicle may be approaching a situation where rollover is probable. If such a situation exists, the RSC system applies preemptive action. When activated, the RSC system adjusts the brake torque at specific wheels in response to direct measurement of the vehicle roll motion. By adjusting brake torque, the system can reduce the cornering forces and, therefore, the total roll moment acting on the vehicle. Systems with RSC have an additional roll-rate sensor located within the sensor cluster and additional programming within the ABS module to help control the vehicle during sudden maneuvers.
    Information from the roll-rate sensor is fed into the ABS module. The computer uses information from the ABS wheel speed sensors, the throttle position sensor, the steering wheel angle, the steering wheel rate of change and a yaw rate sensor that measures the change in vehicle direction. If the computer determines from all these inputs that conditions exist for a potential roll over, the system applies one or more brakes and reduces engine torque to make the vehicle more stable.
    If the event is severe and the driver's foot is not on the brake, the brake pedal moves to apply higher brake forces. A whooshing sound can also be heard from under the instrument panel in an event this severe .
    I strongly suggest you have this vehicle towed to a ASE certified repair shop that knows this system !

    Brakes go out at speeds above 60 mph


    I would say that the module they are refering to is the module that allows even distribution of fluid pressure to all the brakes evenly. The exact name of the module escapes me at this moment, but that is what I would recommend in order to fix this problem. As for the pump, this the master cylinder. It also has a check valve that could be a factor in the uneven pressure at higher speeds, but I would start with the distribution module.

    My 1999 Chevy Silverado 1500 Z71 makes a clunking noise and feels like it got rear ended if I drive it for an hour or so non stop. It seems to be when it shifts from 1st to 2nd gear. I had the ******...


    No one can tell you what it is.This is the operating characteristic of your transmission and customer do object to the noise or clunk and dealer discourage the repair. This is TSB 03-07-29-004G. Let me give you a partial copy. INFORMATION
    Bulletin No.: 03-07-29-004G
    Date: December 15, 2010
    Subject: Manual Transmission Operating Characteristics
    Cold Operation
    Manual transmission operation will be affected by temperature because the transmission fluid will be thicker when cold. The thicker fluid will increase the amount of force needed to shift the transmission when cold. The likelihood of gear clash will also increase due to the greater time needed for the synchronizer assembly to perform its function. Therefore when the transmission is cold, or before it has reached operating temperature, quick, hard shifts should be avoided to prevent damage to the transmission.
    Backlash
    Backlash noise is created when changing engine or driveline loading. This can occur when accelerating from a stop, coming to a stop, or applying and releasing the throttle (loading and unloading the driveline). This will vary based on vehicle type, build variations, driver input, vehicle loading, etc. and is created from the necessary clearance between all of the mating gears in the transmission, axle(s) and transfer case (if equipped).
    Shift Effort
    Shift effort will vary among different style transmissions and synchronizer designs. Usually the more heavy duty the transmission, the higher the shift effort because of the increased mass of the components. Shift effort can also be higher in cold weather because the fluid will be thicker. Medium duty transmissions will not shift as quickly as a Corvette transmission. To reduce shift effort, do not attempt to rush the shift - allow the synchronizers to work as designed. Shifting harder will only increase the chance of rushing past the synchronizer leading to grinding while shifting.
    Non-Synchronized Gears
    Some light duty truck transmissions in 1st gear (creeper-gear) and reverse gears in various transmissions, along with all gears in some medium duty transmissions, may be non-synchronized. This means there is not a mechanism to match input and output shaft speeds to allow for a smooth shift. This function is left up to the driver. This can be noticed if a shift into 1st or reverse is attempted while the vehicle is rolling or before the input shaft stops rotating leading to a gear grind. The grinding can be reduced by coming to a complete stop and pausing for a moment before shifting into the 1st or reverse gear. Some slight grinding can be expected. In medium duty non-synchronized transmissions, the driver must match input shaft (engine) speed to output shaft (driveshaft) speed with every shift. This can be accomplished by double clutching, or by using other methods. If the driver is not able to perform this function properly, there will be gear grinding with each improperly completed shift. Driver training may be required to correct this condition. Clutch brakes are used in medium duty non-synchronized transmissions to allow a shift into gear at a stop. The clutch brake is used to stop the input shaft from spinning, allowing a shift into gear at a stop without grinding. The clutch brake is activated by pressing the clutch pedal all the way to the floor. When the clutch brake is used, it is possible to have a blocked shift with the vehicle stationary. If this occurs, engage the clutch slightly to rotate the input gear to allow the shift. The clutch brake is intended to only be used while at a stop. Care must be taken to not activate the clutch brake while shifting between gears. This could lead to excessive grinding or a blocked or missed shift.

    Rear breaks lock up at slow speeds. when traveling from 0 to 10 MPH if breaks are applied abruptly 1 or both of the rear wheels will lock up before the front breaks seem to engage, especially on wet road....


    `right one of two problems ,firstly remove the rear drums and check for a fluid leak as a slight smear of fluid will cause the exact problems you describe ,if the rear shoes are dry then push the cylinder each side to make sure its not seized ,secondly check the load sensing valve which will be under the chassis above the back axle,if that appears ok and not seized then remove the master cylinder and take the piston out and check the rubbers and the cylinder bore for wear ,but mainly this fault is caused by the brake shoes having a slight amount of brake fluid contamination and it causes the brakes to grab

    96 F250 can't shift out of park


    NOTE: Your vehicle is equipped with a

    brake-shift interlock feature. This

    feature prevents you from shifting

    from P (Park) unless you have the

    brake pedal depressed. (The ignition

    must be in the ON position.) If you

    cannot shift from P (Park) with the

    brake pedal depressed:


    1. Apply the parking brake.

    2. Remove the key.

    3. Insert the key and rotate one position
    clockwise (ignition in the OFF position).

    4. Apply the brake pedal and shift to N

    (Neutral). (If the vehicle is shifted to P

    (Park), you must repeat the previous steps.)

    5. Start the vehicle.


    If you need to shift out of P (Park) by using the

    alternate procedure described above, it is

    possible that a fuse has blown and that your

    brakelamps may also not be functional.


    WARNING

    DO NOT DRIVE YOUR VEHICLE UNTIL

    YOU VERIFY THAT THE BRAKELAMPS
    ARE WORKING.

    check fuse 13 based on the attached diagram.

    If this fuse is bad replace it. If it is not bad, blows again, or continues to be stuck in park then you need a new brake interlock switch that can be found on the brake pedal up underneath the dash.mustang_guru_2.jpg

    Shiter


    couple things apply brake when shifting out of non running vehicle or you should be able to with key still on the on position with engine not running apply brake shift down to nuetral then start vehicle up with applied brake shift into park

    if this isnt working then inside key cylinder the k.c. pin that locks the column is broke or wore down you should be able to at least get the blazer into neutral to shift out back to park

    under neith the blazer there is a saftey shift module that if this is worn it wont let you shift or you can shift with dead engine and no brake applied this might need to be replaced by tranny tech

    the other way to unshift the shiter is have a buddy with you this is a little finness in what i say next
    chock the wheels from rolling on a hill disengage the saftey brake now start pushing on the vehicle with engine off back and forth this disengages the 4x4 locked hubs gotta roll back a little but be sure not to let vehicle run over buddy

    these are just a couple things off the top of my head that i can think of since im not actually there to see in person i hope this helped
