got my 300ex back from the shop to day and got a few ?s

[bigbadbrad]

ok i went to pick up my 300 from the shop a few hours ago. had steel braided brakelines , twist throtle, handel bar and park brake bloke off put on and i need some help. the steel braided brake lines dont seem to help because i push on the pedal and it is still all mushy. the wheels still lock but the brakes are all mushy and i heard a hissing and thought the bleeder valve was not closed all the way but it was and i looked closer and there was brake fluide with air bubles coming out of theparke brake block off. now i know i need to bleed my brakes again. what i am asking is what kind of sealent do i put in my block off i read a post a while back and i think it said silicone rvt sealent. i have a james lucky old style blocke off (not the new wavey one of the finned one the one that says lucky on it) it does not have a gasket in it, but it does have a little hole(pinkey diamiter) in it. so where do i put the sealent and what kind do i use?
and i like the twist throtle so far. i will find out if i am going to keep when i go on a trail ride in may(when the trails open).
sorry about it being so long but i need some help and i am really :confused: and need to know what to do.
thanks

There shouldn't be fluid behind the blockoff plate. Sounds like you have a bad o-ring around the piston pin that operates the e-brake. The RTV just keeps water from getting behind it.

what do you mean? i took off the park brake. i put a block off on. I am :confused: wherer is the o ring? is that expensive to fix?
my park brake block off looks like this but it says jl on the side

my pb block off looks like the one in the exriders.com store but it has jl on the side which stands for james lucky

advice.....don't let local shop work on your quad.
you've could of put those parts on yourself with any trouble. i never bring my quad to the local shop unless its somthing major in the motor.

i did not go to a shop i went to a r=freind that is a very good mechanic and it did not cost much at all
i know i could have of put all that stuff on my self but i dont have the time because of school ok

There is a pin that is on the back side of the caliper piston. There is 2 o-rings on that pin that are most likley bad. You need to buy a caliper rebuild kit. I don't think they are very expensive.

[bigbadbrad]

yup you are right. ineed to replace those o-rings. i took of my pb block off and i found part of the o-ring. thanks everyone that respondeed to my post. i am preety sure i am going back to my thumb throttle. i dont like the twist on a quad.
