Nissan Fast Check - Brake Master Cylinder

[rs73]

Anyone has Nissan FAST?

If you do, can you check whether any parts of the brake master cylinder differs between the brembo (track) & non-brembo models?

Thank you

Will it be any differences to change the brake cylinder?

I know that the Brembo are bigger compared to non brembo one.

[rs73]

see the link I pm'ed you earlier?

upgrading bigger caliper without upgrading master cylinder might be the culprit to 'soft' pedal feel, that is if you have tried bleeding the brake system and flushing/changing the fluid with new brake fluids

which link again?

[rs73]

cant be bothered searching it again, check your pm, from this morning

btw the Brake booster is the only that are different.

[rs73]

M215T for brembo

had my brakes bleed by nissan dealer yesterday during the 60k km service.

slightly better. still feel a little bit soft, although according to them wouldn't cause an issue.

perhaps time for a set of braided brake lines?

hey Rianto,

Just to let you know my brake is firming up after a Drive around the town. So mine all good now. but i did use the Nismo Braided line, probably that's what made the differences.

I use the Motul 5.1 too.

Cheers

I read somewhere dot 5.1 absorps moisture quicker than dot 4, as it's more for motorsport/performance where it's expected to be flushed/replace a lot more often than dot 4

that said i haven't replaced mine since april :-o

hmmm not sure being motul 5.1 reckon it's a long life, but not sure how long is long life lol.

Motul 5.1... is great and lasts for just as long as normal... in a sealed system it can not absorb anything but heat.

No Silicone and works on the GTS-T and the GSXR

U should never re-use an open bottle, unless it has been sealed very well.
