soft brake pedal after sport brake upgrade

clintfocus · 04-28-2013, 02:36 AM

gravity bleed is the best way, takes alittle time, and you need alot of bottles, but it works the best, dont cross contaminate old and new fluid, and it can be done alone. I used to work at Brembo NA and this was the method we were told to use

You only need ten minutes and 1 quart of your favorite brake fluid.

^yeah i know, a little time is about 10-15 mins no? lol

^ i usually just run two bottles of Motul RBF 600 through it on a gravity bleed, and BS on facebook till its done LOL :P

you could have a loose zirc on a caliper too? have you lost any brake fluid since flushing?

Have a lot of people going from base to a BBK actually upgraded their brake booster? I feel like this is the first time it's come up.

JARblue · 05-03-2013, 08:44 AM

very interesting that I haven't seen anything about the different brake boosters in the base and sport with regard to this upgrade...

Z1 says you need a new oil line for the caliper (hardline).

I'll be getting it fixed in the next week or two. I've searched and people that upgraded never changed the booster.

Has to be a air bubble.

They talking about the stainless steal lines?

Ohhhhh lol

Just guessing myself but just from what I've read seems like a popular upgrade.

Ni55anPat · 05-04-2013, 09:30 AM

Yes there is a metal line suggested from Z1 to upgrade. Which I did.

diddy535 · 05-04-2013, 10:24 AM

Still soft?

this is a silly problem and thing to ask, but its a common mistake on brake swaps. Are the calipers on the wrong side? Its very easy to do and is almost always the case when my powdercoating customers have issues, although on some calipers, its not as obvious as on these. bleed screws on top.

Ni55anPat · 05-06-2013, 11:13 AM

Bleed screws are on top. Metal like installed. Just did a re-bleed 3 more times and its good to go.

Thanks for the help.
