My battery went flat now my motor is locked up

[Guest]

Can some one help me out i have a 96 wrx ra and my battery died then wen I charged it it wouldn\'t start and when I try roll starting it the wheels just lock up what would be causing this problem

[94 Leone]

Handbrake, in wrong gear, brakes seized because oil not being pumped through brake booster ergo: foot brakes stuck on.

[DRFVDR]

try jump starting it, your battery is probably toast that is why even though it is charged it still wont start, if trying to push/tow start use 2nd or 3rd gear NOT first

Sorry man, what

[94 Leone]

Lol, the commas were trying to list.

I was pointing out that he could have the handbrake on.

Or be using the wrong gear.

Or if he\'s used the foot brakes with the car off, it\'s likely that they\'ve seized on. Because no oil pumping through brake booster or something like that, so they just stay on.

Not quite sure the exact physics of it, but that\'s something how it works.

I repeat Marky, what?

Oil doesn\'t pump through the brake booster, it\'s vacuum actuated on Subarus...

[gazzy2000]

make sure when the battery deflated it didnt fall off and get wedged in between the chassis and crank pulley

[Joker]

are you rolling all the wheels in the same direction?

[ADIKT]

you sure your engine didnt die/cease of oil starvation?

And if it\'s vacuum actuated then with the motor off it won\'t retract, it\'ll let you push the brakes on, but not release.

Thus why when towing a car, use handbrake rather than foot brake in second vehicle to slow down. I may be looking like a total ar$e but meh.

You can pump the brakes with the car off but you get next to no pressure as no vacuum assist off the booster. SO when towing it will feel like you have no brakes but its just the fact you have to press like a weight lifter to get any action.

I thought being young made you invincible not unintelligent.

[petrolheadjman]

What on earth?

Look at your brake booster, there is no where for oil of any sort to enter or return? The only line going into the brake booster is a vac line

i\'m sorry but you\'ve made a fool of yourself but at least you know now

[dean.ryan]

This was a laugh to read. Thought I might just say

[94 Leone]

Fool level = over 9000

Haha... ehh.

I hate it when you hear some vague peice of information and it sounds feasible: so you go on beleiving it...

Bahaha; happy to be comic relief.

Anywho: has OP sorted problem, or are we just gonna beat up on the green 17 year old with zero form of formal mechanical education? :

Haha lol I look really retarded in this thread lol

[dean.ryan]

I\'m 17 with little mechanical knowledge, maybe I should remove myself also

On the other hand, thing with the brakes being locked up. How can you crash start it if you can\'t get it to move in the first place? Someone didn\'t think that one through.. Maybe it\'s just a coincidence that maybe the centre diff has shit itself or something like that? Unless they\'ve got the great idea to try do it in first..

Feel sorry for the fella pushing it.. Face + rear window hahahah

[Swindog]

It should roll or you should be able to roll the car so if you cant AND you have handbrake off, in neutral then you have some other problem.

Id be jumping it to see if it starts. The rear discs could be stuck on even with the handbrake off. They do that sometimes if its been wet. At least my last two wrxs have done it periodically if sitting for a couple days after rain.

centre diff could be stuffed causing it drivetrain to lock up, does it have a dccd ?? could this go to full lock with no power ??

dccd would be fully open with no power
