Spongy Brake Pedal

Ok so i replaced front and rear brakes last night. But now I my brakes pedal goes to the floor. I never lost any fluid and my reservoir is full. It looks good and clear. I did pump the pedal before i started it.

Was there some kind of trick I should have done before starting it up? Or do I need to bleed them?

 

Do you have a vacuum booster or the hydraulic one?

 

I really don't know. It's a 2013 4.0l
Truly this is the first time doing anything with this truck. It's been such a great truck that I haven't had to touch it.

 

Your rear brakes are more than likely out of adjustment. With you back tires off the ground there should be a slight resistance when you spin them backwards.

 

Vacuum boosted looks like this.


Hydraulic boosted looks like this.

 

I have tried to back up a few times to see if they would set. It had got dark and cold on me so i had given up at that point. lol. I will pull the wheels back off and try to readjust them.

 

OK Dm93 they are vacuum.

 

That is a possibility, you want them just dragging on the drum slightly. A good test to check them is to set your parking brake and see how far it travels, if it goes all the way down they are probably too loose.

 

Ok then I'm betting rear brakes aren't adjusted up correctly.

 

Ok thanks. I will try it out tomorrow.

 

Tacoma drums don't self adjust backing up. They adjust with parking brake use. But if they are really far out you need to do it manually first.

 

Maybe you just need to bleed the brakes properly. Just youtube it

 

Do this to properly adjust the rear brakes:

Hopefully you didn't pop out a wheel cylinder piston from the excessive movement.

I find it odd replacing the rear brakes on a 2013 so soon. How many miles?

 

What is a "rear drum gasket"??

Edit: Ok I found this by a poster who was equally puzzled by this as I am. I have never seen this before... even though I have had my drums off to inspect them.

It is just a piece of paper that goes between the drum and the axle. I've never installed one.... It keeps the axle from rusting onto the drum.

 

I usually just put a schmear of anti-seize there. Maybe next time I'll replace the gaskets.

Assuming the brakes weren't "opened" (some people crack the bleeders to make squeezing the caliper pistons back easier), I would think it's as others have said - the rears aren't properly adjusted.

As Raylo stated, the drums adjust by use of the parking brake. If the shoes are adjusted too loose, it takes a LOT of parking brake activations to adequately move the shoes. I read somewhere that it took a guy about 50 activations before the shoes moved enough because the guy was too lazy to just take the drums off and adjust them properly.

 

Thanks everyone for the help. Problem has been solved! The self adjusters needed to go out more. She stops like a brand new truck.

And to answer your question Jimmyh, It has 140k miles on it. I only changed them because i could here them. I have done some heavy pulling with it the last 2 years.
