Type M Brake Upgrade Probs

[1400r]

I did my non type m to type m brake upgrade over the weekend as I got some 4 spotters for free of my boss, however I didnt get the type m rotors.

Everthing went on fine I had a little trouble bleeding the brakes but every thing seems fine now the brakes seemed really firm until I turned the car on and went for a blat. The brakes have to be almost on the floor before there is any retardation I assumed that the smaller stock rotors wouldnt be a problem as it would just be similar to running worn brake pads?

I also used the pads that were with the 4 spotters rather than buying new ones as I wasnt planning on doing the upgrade till I had the funds for the set of types front rear and new pads.

1. Should I buy a set of new pads and see how they go (dont really want to do this as it may only slight help but not fix the problem)

2. As the pedal feels very firm when you pump it up, have I not bleed the brakes correctly? (I printed of the s14 manual and followed it after searching for hours on end)

3. Should I try and get some type M rotors as the non ones are to thin?

4. take it to a brake place and confuse them with the whole type m non type thing and end up spending heaps of cash replacing brake master cylinders, getting the 4 spotters rebuilt etc because they dont know what there doing

not 100% sure but sounds like a air lock, i would try giving them a good bleed and make sure the master cylinder is full while doing so

yep I will have a chat my boss to see what I'm doing wrong sure seems like there's something wrong as there still firm when the cars turned off?

my boss and the Japanese mechanic rebleed the brakes still no joy so now we think I'll need to also change to the type m rotors

[urbanoperations]

what rotors are you using?

you cant use non turbo rotors on Turbo 4 spot calipers as the rotors are to thin , change to the r32 GTST rotors as they are thicker and they are the direct fit for that caliper....

You might also want to check which size your master cylinder is.. it's stamped on the side.. gts-t is 15/16

it is a gts-t just not a type m
