Brisbane- Beetle Brakes - help needed to bleed
Can someone please come and figure my Beetles brakes out.
Brand new brakes all round including dual MC and solid brake lines, wheel cylinders etc.
The Pedal goes hard but the wheels can still be turned with only moderate brake drag being felt. I've done everything I can think of and need someone
knowledgable in VW's to get it to work.
Will pay for your time.
Cheers,
Mike

Hi
Once You have drained the brake circuit on a beetle , You can have lots of problems....
I have heard of people bleeding the master cylinder on the bench?? How You do this is beyond Me.. lol
it took Me probably 4 bottles of brake fluid when i did My brakes... maybe more... lol
You need to have the rear brake cylinders above the master cylinder so all the air will flow to the back and out the bleeders - let it sit for 1/2 an
hour or so..
so, I've been told by a brake mechanic...
also, bleed the master cylinder.... air will go to the top or will stay in a crevice etc... or near a brake switch....
maybe pressure bleeding will work better..??
flowing brake fluid should take air with it...!!
best of luck

if you didn't replace the rubber hose they are probably blocked with shit.
or your master cylinder push rod is over adjusted.

Ok first off, adjust your brakes so they drag a touch with the park brake off,bleed both circuits of the master cylinder then start bleeding from the
rear left, then rear right, front left and front right. Use the pressure method, regularly check the fluid level and top up. Adjust your hand brake,
then take it for a slow drive if possible to bed in the new shoes, when you get home adjust your brakes again, they will be out a bit due to the shoes
moving and bedding into the drums.

Make sure you use a one way valve on the nipple end. saves any bleed back issues.

x2. Normally we bleed the master cylinder prior to fitting and also the wheel cylinders,fit them to the car,open the bleeder with a tube going up
above the cylinder,let the fluid gravity flow and then a bout 6 slow strokes,hold the pedal down and close the bleeder.continue to the next
wheel.Usually the longest line and consecutive to R/H/F.If you still have trouble you you can block 3 lines with line crimps to isolate the wheel with
the problem & bleed accordingly.
