Title: New brakes foot flat to the floor :-/
Post by: Mattyj on 05 July 2014, 16:11
Just fitted my bbk and braided lines bleed brakes with a one man bleed kit till no more bubbles took for a spin foot goes flat to the floor :-/ guess it just needs another bleed but if not, apart from the unions not being tight any ideas?

I think you need to run the abs pump to bleed them properly ?
Get a VW specialist to bleed them or main dealer,
May be a silly question but have you fitted your calipers the right way up ? Bleed nipple to the top,
As some calipers off different cars have them fitted to right or left of the disc as you look at it, if the nipples are at the bottom it may trap air inside, and also the leading piston which is usually smaller will be on the trailing side,
I think a full fluid change at the dealer is only about £45
No need for up rated fluid, use the vag stuff that's all I use and never had a problem with it, if it's good enough for a Veyron it's good enough for a golf  :grin:

Bleeding (normal):
Adhere strictly to work sequence when bleeding brake system.
–     Connect brake filling and bleeding equipment -VAS 5234-.
–     Open bleeder valves in specified order and bleed brake calipers.
1 - Front left brake caliper
2 - Front right brake caliper
3 - Rear left brake caliper
4 - Rear right brake caliper
Use suitable bleeder hose. It must sit tightly on bleeder valve so that no air can enter brake system.
–     Leave bleeder valve of each brake caliper open with bleeder hose fitted until brake fluid discharges free of air bubbles.
   

Subsequent bleeding
Carry out subsequent bleeding when:
t     brake pedal travel is too long or so-called »soft brake pedal«
t     in vehices with EDL, EDL/TCS or EDL/TCD/ESP a chamber in the brake fluid reservoir is completely empty. This occurs e.g. in the case of brake system leaks.
Subesquent bleeding requires the assistance of a second mechanic:
–     Depress brake pedal firmly and hold.
–     Open bleeder valve on brake caliper.
–     Fully depress brake pedal.
–     Close bleed valve with brake pedal held down.
–     Release brake pedal slowly.
This bleed sequence must be carried out 5 times per brake caliper.
Bleeding sequence:
1 - Front left brake caliper
2 - Front right brake caliper
3 - Rear left brake caliper
4 - Rear right brake caliper
A road test must be carried out after the brakes have been bled. When doing this an ABS regulation must be performed at least once.

Think just need bigger master cylinder they work just a tiny delay on pedal travel
