Brake pedal adjustment

adjustable pedal relay Adjustable Pedals System Components
The adjustable pedals system consists of the following components:
• The adjustable pedals position switch
• The driver seat module
• The adjustable pedals relay
• The adjustable pedals motor
• The brake pedal position sensor
Adjustable Pedals System Operation
The adjustable pedal system is controlled by the adjustable pedal switch or the driver seat module and operation can occur only while the transmission selector lever is in the PARK position. The adjustable pedal assembly is moved forward or backward by a motor, which is fixed to the brake pedal actuator with a drive cable to the accelerator pedal actuator. The adjustable pedal motor is operated by 2 motor control circuits from the adjustable pedal relay. In an inactive state, both of the motor control circuits are closed to the ground contacts within the relay. The relay coils may be energized by the relay control circuits from the driver seat module or the adjustable pedal switch. When a relay coil is energized, the motor control circuit is switched to the battery voltage supply contact. The adjuster motor is bi-directional and the direction of the pedal assembly travel is determined by which of the motor control circuits is closed to battery voltage, while the other remains grounded.
The driver seat module monitors the location of the adjustable pedals using the brake pedal position sensor. The brake pedal position sensor is supplied with 5-volt reference and ground circuits from the driver seat module. The position sensor signal circuit is referenced from ground within the driver seat module. The signal voltage monitored by the driver seat module ranges from 0.39-4.58 volts and is determined by the wiper location on the resistor within the position sensor. The position sensor circuit voltage level is used by the driver seat module to determine the position of the adjustable pedals when storing or recalling memory position settings.

If handbrake has excessive travel and the brake pedal is low then you havent set the rear brakes up properly ,if a drum then you clean the lip on the edge of the drum so it has a bevel then you manually adjust the auto adjuster till the drum just slides over then tap outer edge of drum wth a small hammer to level the shoes and then see if you can then adjust the auto adjuster up a bit more .Also when taking the drum off again make sure that the handbrake mechanism lever is right back ,Now if you adjust the brakes on the handbrake cable then it will be out of square and will not work on a brake roller tester ,and the footbrake will still feel spongey then you get a inspection failure for excessive pedal travel and low handbrake efficiency ,this model of car should be able to lock the rear brakes up at 30mph when jerking the handbrake up hard and it shouldnt have more than 3 clicks when done correctly

A clutch pedal takes MUCH more travel to function correctly, when compared to a brake system...

A clutch needs to be replaced (maybe) when it SLIPS, Chatters, Or fails to release...

Other than that, the clutch will need to be adjusted to allow for total release of the relese bearing when pedal is released, and full disengaugement when pedal is depressed....Have a mechanic look at the adjustement, as proper adjustment gives longer clutch life. This is a periodic adjustment item.

Did you adjust the brake light switch correctly? To adjust the brake light switch, first press the brake pedal down a few inches, then pull the switch plunger rod out of the switch toward the brake pedal arm, as far as you can without using excessive force. Next, return the brake pedal to the pedal stop position against the pedal stop and pull the brake pedal toward the rear to push the brake light switch actuating plunger rod into the switch housing limited by the travel of the brake pedal arm rear travel stop position. This procedure automatically adjusts the brake light switch correctly.
If the brake lights still don't turn off with the brake pedal released, check the brake pedal arm for sticking or binding that is preventing the brake pedal arm from returning fully to the pedal stop when the brake is released.

your rear brakes are worn or the self adjusters are rusted, assuming you have drum rear brakes & not disc pads in the rear.
Try backing up several times with very hard stops to activate the self adjusters. If you don't back up much, the self adjusters can not work. Parking brake will be adjusted at the same time.

please rate.

There is an adjusting rod behind the master cylinder or at the brake pedal. The dealer should adjust this for you as its travel distance is very important.

take the back brake drums off ,clean the lip out with a small angle grinder then manually adjust the rear brakes and the brake pedal will be nice and hard with 3 clicks on the handbrake ,nice job when done and it all works ,their is no adjustment on the brake pedal only on old cars with rod and cable brakes

I think your saying you have a spongy pedal. have the brake system checked for leaks ( externally as well as internally eg master cylinder) and wear. If a-ok then have them bleed the system.
Now if your saying there is a problem with pedal travel
that has to do with pedal rod adjustment( which is only adjusted after replacing a master cylinder or booster)

your brakes are not adjusted or the brake pads are worn out. check and adjust.
