finally at brakes stage - need some help

[Angelo Amato]

right getting close to completing my fastback.

just finished off the brakes and bled them.

this is the spec :-

FRONT - Audi 2.0L 1989 coupe front calipers on stock type 3 discs (fitted late type 3 spindle with minimal mods)

REAR - VW Mk4 Golf rear (alloy) calipers on Mercedes discs on turned down type 3 hubs, custom caliper brackets (discs just a bit smaller than stock type1/3 front ones)

MASTER CYLINDER - Audi 80 ATE new - 20.64mm bore

HANDBRAKE - hybrid Mk2 GTI outer sleeves (shortened) with new inners to suit rear caliper fitment and handbrake.

BIAS - dial-in brake proportioning valve on rear

NOT a neck breaking setup (a la porsche) but wanted to create my own.


RIGHT !

Now the setup has been on the car before the big resto,etc... and I have driven it (only very little) as above BUT with the stock type 3 m/c before.

now bled them OK the other night (pressure bleeder), did it a couple of times to make sure.

I have a couple of issues ( that i had before, but thought would be resolved this time!) I need to sort out....

1. EXCESSIVE PEDAL TRAVEL - i had this before with the old M/C. was hoping slightly larger bore of new one would solve this. pedal is firm and brakes function, but just a bit too much pedal movement for me.

2. HANDBRAKE - again works but efficiency is in doubt. pull up hand brake lever all way and not feel any resistance on it.

nobody on here seems to complain about excessive pedal travel on large brakes EVEN with a stock m/c ! I am using relative small bore calipers not huge brembos.

the master cylinder was chosen as it fitted nice and bores seemed to suit my relatively mild upgrade.

99% confitdent on there is no air in system. one quirk is because i run anti-bump steer kit on tie rods (upside down) clearance to caliper is tight and i run the calipers on opposite sides so bleed nipple clears (points down instead of up). BUT when i bleed, i slacken them off and bleed in with nipple up.

Any help,comments,critisisms appreciated !
