gday mate, im after more info on the brake master cylinder. Is it from an ABS or non-abs car? (I need non-abs) Whats the bore size? Do you happen to know if its a bolt on to an S13? thanks, -Ark

nah the s14 brakes are basically the same as Z32 300ZXs (except all the s- series have iron calipers, whereas the z32 and the r- series have alloy units) http://tuning.silviansw.com/brakes.html The reason the pedal is so soft and braking performance is bad is because my small master cylinder simply cant push enough brake fluid into the comparitively huge 4pot calipers. I need to push the pedal all the way down to move the four pistons in the same amount as the stock single piston caliper would be with only half that movement. A bigger master cylinder would push more fluid for a given amount of pedal movement. The pedal would feel slightly firmer because you have to move more fluid for each unit of distance moved - move more mass(fluid) and youll need more force(pedal firmness) Do you happen to know the master cylinder bores? thanks -Ark

ive already got s14 brakes - perhaps you meant the master cylinder? S13 ca18de(t)/sr20de = 250x18mm discs, single piston calipers (what I used to have) S13 sr20det = 280x22mm discs, single piston calipers S14 = 280x30mm discs, 4pot calipers (what I currently have - but with a small master cyl)

gday all, ive got an S13 silvia Q's (ie. non-turbo: crap) and have recently converted to 5-stud w/ s14a silvia brakes at the front (stage1 is brakes, stage2 is turbs conversion, stage3 more suspension work). The biggest problem on tap now is the brake master cylinder. Non-turbo S13s (and CA18DETs) have what i believe to be a 13/16" master, and SR turbos have 15/16" units. Being a non-turbs, I have a pathetically small master cylinder, and with these nice 4pot calipers (s13s all have single piston jobbies) my pedal goes all the way to the floor without a sweat. :ghost: I eventually want to upgrade to r32 gt-r gear all round (non v-spec/brembo - sumitomos i believe?) but for the moment the s14 brakes will do fine. I like a very firm pedal (engages quickly) so im thinking a 1" master cyl would be the go... opinions? hmm perhaps I should make a point here... Id like information on all the brake master cylinder sizes from the skyline range - eg r32 gts-4/gts-t/gt-r/vspec/vspecII, r33 gts-25t/gt-r etc etc Im told that ABS and non-ABS models have vastly different master cyls and thus arent interchangeable, and given that my car is NON-ABS, are there any units that would suit my needs? Im sorry to babble this load of crap... Thanks everyone, -Ark
