2003 S10 parking brake pedal won't stay to floor

It's a manual transmission so it's an important feature, lol. The parking brake holds the truck in place if I keep my foot on it, but the mechanism that holds the pedal to the floor is busted or something. Was hoping you could tell me about this mechanism. Thank you very much.

    Same issue here

    It appears that the locking portion of the parking brake mechanism is broken on mine too.

  • nawzyah Feb 08, 2009

    What exactly is the name of the broken part? Knowing this would make the search a lot easier.

    I have the same pproblem, took out the entire assembly, cut out the rivits holding it together and found the cheap broken plastic piece that makes it work. How poorly could they design something 99% metal with the critical piece plastic, and no way to rebuild it? The assembly was made in canada with some parts from mexico. So much for the american made truck. I just started looking for a replacement, I do not want a junkyard replacement because it is probably about to break like all the others. - sps

My '03 S10 with manual transmission had the parking mechanism fail. I could push the parking brake pedal to the floor and it would not lock in place. To take out this mechanism, pull the plastic sidewall off next to the parking pedal, then unscrew the plastic panel underneath the dash, which is above the gas and brake pedals. The front plastic panel can remain in place. The parking mechanism is held to the sidewall by two lower hex head screws (easy to take out) and one above the pedal arm (this takes patience to remove). Feel around for this upper nut - it's there. I used a small extension on my ratchet with a deep wall socket. The upper nut is attached to a stud and this will align the parking mechanism when putting it back on. Once the mechanism is out, take off the parking and brake release cables, the parking brake wire connection, and you're free to see if it can be repaired. The mechanism on my S10 had one end of the spring off to the side, and once put back into place, the repair was made. Good luck!

I have the same problem, and have a solution. what is wrong is, there is a tooth that locks into a half moon gear in your break assembly.and that tooth is broken. since the assembly is completely riveted together. you cannot "fix" it what you have to do is take out the old assembly and replace it with a new one, now be carefull taking out the old pedal there are several vital wires in your way and it is difficult to even see let alone remove the top nut. after removing the pedal. there is another ordeal. finding a replacement. im not one for paying retail price so i checked out a junk yard.Problem. there is a similar assembly on older models (the ones you see in junk yards) its simmilar but will not work. i am hoping to find someone on craigslist parting out a late model S10
i hope this is helpfull
in the mean time, leave your truck in gear, first or reverse(depending on the angle that you parked), i have the same problem, mine is a manule as well
if you need further advice feel free to email me

    2001 s-10 4 wheel drive, if it is still out take another look at the release spring, on mine for some reason the spring or dog that releases the break was pushed to far and was wedged keeping the break from locking, twist with a screw drive and the dog was dislodged, it now works very well, another tip squeeze the peaces together to eliminate some of the play. good luck.

What would prevent a 2005 jeep liberty from shifting out of park

this is a feature, on A/T cars. for vast years, !!!
my jeep is M/T and has no such thing, but A/T has this.
This feature, prevents starting in GEAR.
called park lock out, so the Audi lady can't drive over her kids, ( really sad huh?)

Called BTSI: by jeep.
this feature does, not stop starts/crankikng. unless, the shifter is not placed
in park or neutral. (this feature blocks cranking in any gear)

so i must guess, its in park, engine is running, right?
and your foot, is on the brake, and the brake lights do glow behind car, if not the park lock will stay locked.

if you need a schematic, i can send it.
some cars there is a park lock out bypass so you can drive
with no brake lights. (LOL)

the BTSI bypass is missing this feature, in 2006, unlike older cars.
a federal mandate that bypass removal.

check the brake light fuses first of brake lights are dead.
the post back for schematic.
the FSM covers how to fix this on all cars made, (usa car, and forum)
The OEM "factory service manual" buy one and end guessing.
or login to

so does the starter work or not in park or neutral.
this i can not guess from your post. at all.

no starts
no cranks
fails to stay running, engine.
if the key will not crank the engine in park , then try cranking
in Neutral,(this trick uses fresh PRNDL contacts)
if the engine will not crank use jumper cable ump starts from a running donor car, (read paper sheet in cable box, it tells how )

if the car now cranks and starts jumped,that means the battery
was (is) discharged, that can be caused by phantom drains.
all tests are easy, and all take only a 10$ walfart DMM meter.
to find true cause , ask.

try posting what step fails in the operator guide , how to start your engine.
shift to park.
foot on brake,
turn key to crank, does this fail?

2005 yukon will no go in to park

Put foot on brake push shifter all way up. Lol. Seriously of it doesnt go into park your transmission is messed up. Teeth likely broke inside blocking the shift ability. Not common at all. If someone slammed it into park while driving could cause this.

I left my car (Mercedes C180 auto 1994) with a mechanic to replace the back and front brakes. In the process, the mechanic said he had to replace the calipers on the brakes. When I drove the car home and...

I would say one of two things happened. first maybe the parking brake shoes need adjustment. the most common that i see all the time even with newwer cars and trucks, the rear brakes are set up two ways, the type your car uses is the disc rear brakes used to stop the car and then for the parking brake it uses shoes inside the rear of the brake rotor, inside the rotor it gets very rusty and the shoes tend to rust awat from the metal mounting braket it comes on. i see this all the time, when you go to remove the rotor as you slide the rotor off the shoes fall apart and can not go back on, as along as the rotor is not removed it will stay in place, this problem would of occured anyway it would of taken a while longer and then you would of heard noise from rear wheels but it happened sooner due to removing the rotors, its not there fault but they should of called you and told you that you would need parking brake shoes but thought that you may not use the parking brake which is a bad thought in there part. maybe its just an adjustment that need to be made to the parking brake. heres a picture of the rear shoes to show you the metal bracket the shoes come apart from. another thing is that if the rotors were replaced then that explains it more as the old rotors contain rust and build up and that helped make the parking hold bettter.lets hope it just an adjustment.johnjohn2_137.gif

I cannot put the gear on park


Without knowing which vehicle you have, you should first try placing your foot of the brake pedal then shifting into PARK. If this still doesn't work, keep your foot on the brake pedal and have an assistant check to see if your brake lights are working - if no brake lights either, then your brake pedal switch is faulty.

If your brake lights are working ok, then there may be a problem with either the gear linkage to the transmission, or possibly the transmission range switch.

How to adjust parking brake. do you need to take anything apart?

You cannot adjust the cables on a minivan manually. the tension is automaitcally adjusted by the self adjuster on the pedal release.

The park brake cables on this vehicle have an automatic self adjuster built into the park brake pedal mechanism. When the foot operated park brake pedal is in its released (upward most) position, a clock spring automatically adjusts the park brake cables. The park brake cables are adjusted (tensioned) just enough to remove all the slack from the cables. The automatic adjuster system will not over adjust the cables causing rear brake drag.

Due to the automatic adjust feature of the park brake pedal, adjustment of the parking brake cables on these vehicles relies on proper drum brake.

When the park brake pedal is applied the self adjuster is by-passed and the pedal operates normally to engage the park brakes.

When a service procedure needs to be performed on the park brake pedal or the park brake cables, the automatic self adjuster can be manually locked out by the service technician.

I had difficulty shifting my from park to reverse while my ny 2003 Lincoln LS was parked on an fairly steep incline? Is that normal?

You should always use your parking brake. Leave your foot on the brake,then apply the parking brake. If you don't,the only thing holding the car, is the mechanical parking pawl in the transmission,and yes, it could break or fail to hold the weight off the vehicle,and it would roll away,as well as damage the trans.

When i take it from park into reverse it pops really loud

Do you park on a hill, and not use the parking brake?? When folks don't use the parking brake, the car rolls a bit after you put it in park, and take your foot off the brake. Therefore putting pressure on the transmission to keep the car in place. Then when you start up, and throw it in reverse, it will pop, clunk, make an awful sound.

  • A parking brake release control motor (2A843) with mounting bracket bolted to the parking brake control .
  • The vacuum-actuated diaphragm within the parking brake release control motor which is connected by a rod to the upper end of the parking brake release vacuum hose (2B653) .
  • The parking brake release vacuum hose which connects the parking brake release control motor to the engine manifold through a vacuum release switch at the steering column tube (3514) .
  • The parking brake release control motor which is actuated to release the parking brake whenever the engine is running and the transmission is in a forward-driving gear.
  • The automatic parking brake control which has a manual release feature that releases the foot parking brake control by applying force to the parking brake control pedal in the "apply" direction to the point of initial application.
  • The parking brake control will return to the full-release position after removing the force.
