Brakes servo confusion

dominicbeesley · Jun 20, 2012

I'd like to fit 11" brakes to my S3 88". It currently has SLS 10" brakes front and rear but it also has a servo - I'm lead to beleive that this is wrong!

Anyway I have the servo and load balance valve already what else do I need to get other than new back plates, and associated bits.

Should I leave the rears as SLS?

Cheers

my S3 88" had a servo on 10" brakes - i think the later ones had the servo.

i fitted a servo to my 88" with 10"brakes, no problem

I want 11" brakes on the front. I'm sick of running out of brakes on hills round here. So if I can get hold of some TLS backplates from somewhere it sounds like I just need the right master cylinder and keep the existing rear brakes...

Anyone know which part number I need for the master cylinder?
Would I be best chasing down normal 109 fronts or v8 ones?
Any major differences?

Cheers

is your dual system ? the servo systems will run 11 inch drums if std parts

Yes, its got dual circuit brakes but are there not two different dual system master cylinders....must admit I'm getting confused now.

just the one ,earlier servo single line were fitted to 109 variants ,and earlier non servo single line had 88 and 109 variants

Righto I'd just seen there were nrc6906 and nrc8690 that both looked like likely candidates....will just try and source some back plates then....

nrc6906 is dual system (all models) nrc8690 fits 110
