Although I haven't investigated this, I always wonder why this happens...
If you set your parking brake while pointing down a hill or driveway, the car rolls about 6~8 inches forward before it actually stops the car. I can't see what or how the car is doing this since the rear doesn't "sit" when this happens, nor are there any parts in the rear brake that I can see causing this.
Am I the only one who notices things like this???
If your a Sluchbox tranny, it could be that the e-brake isn't grabbing tight enough to hold the car compeltely and its rolling forward till it hits the parking pin in the tranny...
its probably because the mk2 uses a drum in disc e-brake, essentially meaning that the ebrakes are drum brakes so it will roll a little before it gets its servo action going on.
Well Bob, it is a manual tranny, so it's definitely not the trans stopping the motion, although that's the exact feeling I get. Just like I put it in park without any parking brake, and rolling just a bit to where the tranny stops the movement.
And I am familiar with the rear drum brakes on the rear, but what I can't figure out is that when I pull the brake handle, the shoes extend till it hits the brake drum/rotor. So, if it contacts the drum, why would it still roll forward(or back if I am the other way)? The only thing that I can think of that causes this, would be that the parking brake ass'y is able to rotate a bit before hitting something that keeps it from going all the way around.
Btw, thanks for the replies so far!
Inside the rotor there are 2 shoes sitting like this ( )
For them to fully engage the must rotate in the direction of the rolling mass. Basically, they twist until it binds things up.
The E-brake is probably not set tight enough, and the car rolls until the gears mesh into each other, just as if you never had the E-brake on to start with. Tighten that bugger up and see if it makes a difference. I bet you have to pull the handle up almost to the sky before it engages too right?!..
Nope! Already adjusted the ebrake months ago. and it's not rolling back on the gears, this happens in neutral also. It's just a strange feeling that you set the brake, it never rolls forward (if I'm on a hill facing downward), only backward when I'm on a hill facing upward. It does engage though, once it rolls backward about 1 foot or so, but I am able push the vehicle forward once it "hits" this spot. It feels exactly like the brake shoes are completely locked to the hub, but the hub is able to rotate 1/2 a revolution...
Having never taken my ebrake apart I'm not exactly sure how the shoes work but maybe they are of the "leading shoe" design. That's where the front shoe has to make contact with the drum and in effect "pulls" the back shoe into contact with the drum. So perhaps when facing uphill the brake shoes take a bit more rolling resistence before there is contact on the drum from the back shoe.......or maybe there is uneven wear on the 2 shoes causing somewhat the same thing. HTH
Hey there guys just seeing if anyone on here knows of any coilovers that would fit on my 85 supra shes riding on cut springs right now (I bought it like that) and would like to be able to actually park the car in my driveway
I need to replace the front wheel bearings in my ’83, and while at it, I’m replacing the rotors with the Brembo’s that have been sitting in my house for far too long. Prior to the work I was reviewing the TSRM and came across the section for adjusting the preload on the front hub. It mentions...
Hi all - new to forum SYD, AUS based. Have a 1982 Celica Supra 2JZGTE swapped, seeking registration in NSW. Noting this topic has been done many times, but the updates are all from like 2010 and pictures are all gone.
Registration requires me to upgrade the brakes to an 'equivalent' power...
We had my wife's 1984 out for a drive yesterday and the front suspension is feeling a little tired. The strut cartridges definitely need replacement and the steering was not feeling as precise as I recall it being a few years ago.
So I've been looking at various rebuild bushings and the big...
Hey I own a 1984 RA65 Celica GT-S, I have vented disc brakes with the 6.7 diff. I was curious if I swap out my rear end in order to get the 7.5, can I keep my same lower control arms? Or different fitment? Also I having recently lowered my rear and added some spacers so I have a bit of poke in...
