I know I've read this before a million times, but I only found 2 topics when I searched and both had a brake line removal involved.

My friend and I were replacing his brake pads in his crx. I've done this plenty of times, never had to bleed the brakes. We get everything back on, but on the test drive the pedal sinks to the floor consistently, and we must pump the pedal to gain pressure. So we take the wheels back off and bleed the front brakes and it's still happening.

Should I bleed all 4? Are these the signs of a bad MC? If so, why would it go bad only after changing pads?

Thanks for being patient folks.

 

mayb some air got into the brake lines? hope this helps. goodluck

 

Yes, you must bleed all four. Infact you have to look up in the manuel on which caliper to start and end with.

 

Back Passenger side
front passenger side
front drivers side
rear drivers side

I think, it`s been a while

 

Hmm...maybe we'll try that tomorrow. The order is:

1. RR
2. FL
3. RL
4. FR

It's just a pita since we're using a floor jack and not a lift.

 

make sure that when youre doing this, the resovoir doesn't run out of fluid. otherwise you are wasting your time.

 

i always thought it was

rear right
rear left
front right
front left

 

usdmrob has the right way

 

I took the order I posted straight from my Helms manual.

 

it doesn't really matter *that* much the exact order, as long as you start with the end FURTHEST from the MC, and work your way around to the one closest to it.

So that would make it rear passenger side, rear driver side, front passenger side, front driver side. Like usdmrob said.

But you can't really screw it up if you start at the rears.

Edit: left out some words

Then why woudl the Helms manual state it differently?

 

well I dunno.

But a brake system, is a brake system, is a brake system.

When in doubt, you can ALWAYS rely on going from the furthest, to the closest. In that case, it would be rear passenger, rear driver, front passenger, front driver.

That's how I always do it...don't see any reason to do it differently.

 

well said

 

My only comment to that would be to take into account that the brake system uses a proportioning valve. Which links the RR to FL and links the RL to FR. So you almost bleed them individually, this would seem to me to be the reason that the Helms lists it that way. You in a sense are bleeding 2 different systems.

 

i thought it was passenger rear,drivers rear, passenger front, drivers front. the other way that everybody else is talking about passenger rear, drivers front, drivers rear, passenger front i thought was only for cars with ABS. i thought otherwise you are supposed to follow the first way. but what do i know
