My brake pedal goes to the floor with new brake pads on.?
Ceramic Brake pads July 29th, 2009I just had my neighbor put on front and rear brakes on a 98 honda accord. He put on front pads and he put on rear shoes. Now when i brake, the pedal goes all the way to the floor. Do you need to bleed the brakes if you just put on front pads? Or does it just take a while before the brakes start to stick. I put Ceramic BrakBrake Pads on. Any help would be great thanks!
The brake fluid in the resivor is full. He has changed brakes in another one of my cars and my boyfriends car and has never had any problem. Do you think i would be better off taking it to a shop or just have him bleed the brakes…do you think a shop would charge much… I didn’t think that just changing pads and shoes would make you need to bleed the brakes. And, is this unsafe to drive like, other than i know you have to start braking way before b/c of the spongy pedal.
You need to bleed every brake location that you install. Otherwise you end up with the dangerous situation you have now.
You are not activating your brakes and your car will not stop when you need it to. You are just compressing the air in the brake lines. You need the air out so that the brake pedal moves brake fluid not just compressible air.
Should I use ceramic or semi-metallic brake pads on a Chevy Cavalier?

you need to check the fluid level and bleed for sure .

the rear brakes are not adjusted far enough the pedal feeling is controlled by the rear brakes
to fis this hold the button on your e-brake handle in and repetedly pullyour parking brake tillthe pedle feels normal again each tug will click the rear brakes up closer to proper adjust.. i’ll assume right now if you pulled the e brake it would go all the way up with no tension

Just out of curisoity are any of you real mechanics? why would you need to bleed the brakes if the hydralic lines were never opened? or the master cylender was never empty? have any of you really worked in a shop or done it for a living? do any of you know how the self adjusting system on a honda or most other import drum brake system actually works ?

Then your probably need to add brake fluid cause there is less likely enough, or you need to adjust your wheel self adjusters to be even with both wheels on both sides…

No way no how should the brake pedal go to the floor!! He obviously did something wrong so you had better get your car to someone with more knowledge about brake repair before you have an accident. And if it hasn’t dawned on you yet maybe you better keep him away from your car.

Make very certain that everything was assembled as it should have been, and that the brake fluid reservoir has been properly filled. Then pump the pedal about thirty times. This should correct the pedal travel.
If the brake pedal feels springy at the bottom of its travel, you must bleed the air from the system. In general, this should not need to be done with only a pad replacement, but I don’t know what else might have happened during this repair.

Did u "bleed your Brakes?" I know when my ol man is done, i have to sit and push on the brake pedal while he is doing something outside of the car. he has always said "he has to bleed the brakes"

if he didn’t bleed your brake he’s a idot you get air in the line after doing back brakes so take your car to the shop and let them bleed the lines before u have a accident good luck and have a nice day.

adjust rear shoes then "Definetely" bleed brakes.

At first they will go to the floor because the pistons have been pushed back in the caliper to get the new pads in. If you pump the brakes, they should firm up. If not, then bleed.

you have to bleed the brakes .this was not done .once you bleed and fill resiviour then
tell us what happens .if it contiunes check for a leak or hole in one of your lines /brakes are very simple push on the pedal and it will press the calipers .simple as that.if the pedal hits the floor its not presurized or losing presure.

check your rear wheel cylinders and see if they are leaking or the spring are on wrong or master cylinder

If you have front disc brakes with drums in the rear you may have to adjust the rear brakes since the shoes were replaced. Also try pumping the brake pedal to see if it tightens. Normally you don’t have to bleed the brakes when you change pads on disc brakes. However you do have to watch the brake fluid level in the master cylinder to see 1) that it is not below the minimum mark which could mean that air has gotten into the system and 2) when the pistons in the brake calibers are pressed in that the fluid doesn’t exceed the maximum mark. If air gets into the system the brakes lines will need to be bled.
When you first install new pads the pedal is usually soft because the piston in the brake calibers are press all the way in. When you press the brake pedal the piston is pushed out to press the pads against the brake rotor. When this happens the pedal will feel tight.

Experience. I’ve owned three cars and done brake jobs my self.

there are 2 possibilatys, one aie in the brake line…in that case you need to bleed the brakes.the other is a bad master brake cylinder. I tend to believe it is air in the line though

WHen he cracked the bleeder screw to compress the piston on the front calipers, he might have forgotten to tighten it, which would bleed your brakes of all fluid, and get alot of air into the system.

Assuming you have the correct pads, it sounds like a hydraulic problem. Bleed the brakes first and if that still results in soft pedal, you might have a bad master cylinder.
Make sure your back brakes are set up close to the drums. If that was not done after the drums were put back on, it could also cause a soft pedal.

Your neighbor needs to adjust the distance between the rear brake shoes, and the drum.
What’s happening is, when you push on the brake pedal, the slave/brake cylinder has to travel a long way to make the brake shoes press against the brake drum.
Jack up the back of the car again. On the inside of the backing plate (where the brakes are) is a small access slot on the botom for brake shoe adjustment.
With the rear wheel off the ground, rotate the adjuster one "click" at a time untill the brake shoes start to give some resistance to the tires rotation.
Do this on both sides of the car. (rear brakes)
The front brakes do not need to be adjusted.
After manualy adjusting the rear brakes, each wheel cylinder needs to have the air bled out of them.
Air is in the system is compressing when you press down the brake pedal, instead of pressing against the brake shoes/pads.

THIS IS THE PROBLEM……..check break cylinder, they may be worn. you may have a bad master cylinder. there is nothing else ….
