Thread: parking brake relaxing

Every time I get in my car after it has been parked for a day or more,I have to pull up the prking brake a couple clicks to get it to hold.It seems to relax fter sitting.
I dont see any fluid leaks anywhere,and the level in the Master cyl is not getting lower.
Any ideas? Am I slowly losing my Master cylinder?

The parking brake has nothing to do with the hydraulic system.

hmm,you are right.Didnt think of that.But what can cause it then?

Stretching cables maybe? Do you park on an incline? Car in gear too?

The cable stretches over time. Maybe it is time to replace the cable?

Yes I leave it in gear,and yes its on an incline.Thats what messes me up.When I go to start it I have to remember to pull the brake a couple clicks first so I dont roll.

Hmm it hold fine for short periods of time though.It has to sit for a day or more to start to relax.

How are your rear rotors?

My old civic used to see a lot of rear brake use, and it seemed to wear one half of the rotor more than the other. Basically meaning it could slip just a bit off the better portion onto the slimmer portion of my rotor and roll back half a rotation before catching again. Easy way to test this is while driving slow, one click at a time pull your e-brake til it starts rubbing. if it's a constant rub than it's not your issue, if it's on and off you may have some death spots in your rotors.

As the brakes cool they contract. Try taking it really easy for a few miles before parking up at home so the brakes don't heat up.

rear rotor are fine,no warpage,good pads,etc


Hmmm..I have had at least 8-10 B13/B14 over the years.None had this problem.
I am not hard on the brakes before parking it,so I would find it hard to beleive they are hot when I park it.
Its also a few minutes to get through my neighborhood back to the house.Even if I went out and abused them they would be cooled off before I parked.
Thanks for the ideas though,keep em coming.
