i have a 636 and i just bought an f4i too. the rear brake on the f4i isnt as good as the 636, ive changed the pads, blead the line etc but its still stiff to press down on and isnt that responsive, i have a duel system on the rear so that ant affecting it... are fri rear masters troublesome or is there any after market item i can use? cheers

 

are u running oem pads? all I run is oem pads and its night and days difference

 

You talking about the hand brake or factory foot brake?



If I remmber right, 636's are supposed to have JUNK factory brakes, whereas f4i's are perfectly fine


Whats the issue? Is it spongy? Does it not lock the wheel?

 

If you've bleed it correctly and have good pads, then you may have a bad master. The stock F4i masters work great, just find one for cheap.

im talking about the factory brake man, and im running ebc double h pads.. i really have to push down on the brake to get it to work... when i clutch it up to do circles im finding it hard to catch her on the brake, with the 636 i had no problem...

 

the caliper is a sliding caliper , if it isn't sliding it will work like **** ...

take the caliper off and clean and lube the slides also make sure your foot lever moves freely ....

 

did u get brake fluid on the pabs when your were bleeding them?

 

that will definitely make the brakes work like ****

 

no man, all is sweet that way... i think its the master is the problem here... can a blade master fit etc lads?

 

so you are sure the caliper slides ? it is a very common problem

 

usually when the master goes bad the brakes get spongy not hard

 

brake those pupies in or u got fluid on them cuz the stock f4i master almost works to dam good

 

if you didn't get any fluid on them and they are new pads it could be the master or the cal like omr said.Ii have oem pads and and mine are bled good and it will lock the rear tire up very easy without much pressure sometimes i wish it wasn't as easy as it is .

 

i aggree but the double h pads break in fast as hell

 

hmmm.. the brake is very hard... ill service the master so man, cheers for the advice man. keep clutchin it up over there..

 

+1 and wear out fast Oem is all i run not much more $ but you have to order them because no one stocks oem pads

 

where can i get those oem pads lads?

 

yep and the double h pads kill rotors , i alway rum oem i just order a couple sets at a time

 

+1 my buddies rear rotor is fucked up because of those pads
