View Full Version : Ladies and gentleman...please bleed your brakes

Well I just installed new brakes a few days ago. Brembo blanks all around with mintex pads. I also have the A8 kit up front. Braking was still a little shitty. It felt soft and unresponsive. I figured it might as well be old grimey brake fluid thats 86k miles old. Today I bought a big bottle of Vavloline dot4 fluid and called up a buddy to pump the brake for me. I got one of the hand dandy fluid catchers with a magnet and a clear line and the bottle stuck onto the rotor. We pumped the pedal till it was firm and bled. Did this about 10 times in the rear to get most of the old fluid out. About 7 in the front.

My brakes feel awesome now. The new fluid with pads and rotors feels like a brand new car. I also polished up the sliders for the calipers with some high grit sand paper and some mag polish to keep everything centered up. I think the brake fluid is one the most neglected parts of the car. It takes just about 30 minutes to do and and a $5 bottle of fluid. This would be a great weekend job when you are bored.

Did you put something under the brake pedal to make it didn't go to the floor?

Poopie

No? was I supposed to?

Yes. You don't want the pedal going to the floor because it pushes the piston in the master cylinder too far. It can damage the seals.

So what size chuck of wood would you recommend? 2x4 4x4? Kind of being vague. Maybe tell us how far we are suppose to depress the pedal... I want to do this but I want to get it right.

I've read that a 2x4 will do. I never do it this way, since I have a hand pump bleeder.

A piece of 2x4 is perfect.

I've been meaning to bleed my brakes since fall...but the holidays and procrastination have gotten the better of me. I should subscribe to this thread as a reminder to get this done soon!

Thats more so for the old cast iron masters, they rust. Buy almost all of them now a aluminum.

are you saying that bleeding that often isn't required for the new aluminum ones or that it doesn't really matter if you push the pedal all the way down for the aluminum ones.

sry, just got a bit confused.

I just got my flushed by my bud working at VW. THey got a nice pump made by BG which pumps new fluid in and sucks old one out. I put in Castrol GT LMA DOT 4. I read in a Bentley that these brake systems require Super DOT 4 which as higher boiuling points than regular DOT 4. Non the less, the brakes feel great now and I also have the 312x25 rotors up front.

The BG machine does a great job at flushing, but an absolute terrible job at initial bleeds. Never seems to get all the air out. Still have to manual bleed.

Poopie: You put some anti-cease on the sliders?

Poopie
01-13-2008, 01:34 AM
yes anti seize on all the sliders

I have to do this. Everytime I drive any other car their brakes are 10x more responsive then mine, mine actually scare me sometimes, they don't feel 100%..

One bottle of fluid or what?

Poopie

i just bought one big bottle of synthetic DOT4 fluid. It was like 5 bucks.

the car feels ALOT better. Hard braking into corners inspires confidence for better entrances and exits
