R34 Gtt Breaks Issue

[R34GTTM8]

Hey Guys,

I'm having an issue with my breaks. When im just crusiing everything it appears the breaks don't come all the way up and i have to press them in a little harder than normal to engage the break. I took it to the mechanic and he said no break fluid was pumping through its a faulty master cyclinder.

So i paid him and he replaced it.

Since replacing it when i break sometimes the break has no response and falls straight to the floor i then need to pump it to get it to engage again. It has been bled twice and the mechanic cannot find the fault apparently it's fine when obviously i know it's not. It doesnt matter if the car is hot or cold it happens randomly.

This rarely happens anymore however im scared ill rear end someone or hurt myself/someone else.

Any idea's what it could be? Checked air pockets etc to make sure all ok but im stumped. The mechanic has driven it for 5 days without it having the issue and i need my car back.

Sounds like there is a leak, or the master is faulty. Not much we can help with over the internet. Check the calliper halves to make sure the Oring between them isn't weeping.

As a GTT I assume that the car has ABS.

There are bleed nipples on the master cylinder and on the ABS Unit that also have to be bled. I found this out on my GTR - bled the brakes and there was still air in the lines and the brakes were spongy big time.

The fact that it is not a consistent problem is a concern - one of my cars had a dodge bleed nipple on a rear calliper that would leak some times and at other times be fine.

I would be getting a second opinion from a brake specialist who I could trust.
