need help brake problem

need help i bought golf 96 2 door after few days the brake padel start going down.when i check the brake oil it didnt look like brake oil it look like motor oil to me and there was no smell of brake oil .now the question is when i press the brake the paddel go down slowly and when i do duble pump the brake get little tight and then the brake goes down again.so i like to know where could be the problem.

if it doesnt smell like brake fluid then maybe its not! how long have you had the car? when was the last time anyone was doing anything to the brakes??
if its not brake fliud the seals in the master cylinder will no doubt be gone. you will need to replace it. the whole system will need to be drained too.
if it is brake fluid thats in it, the car is 96 so the master cylinder still might need to be replaced. it will either be that or the servo.

what if the person never changed the brake flude?i saw the brake flude it was very dirty and didnt had smell of brake flude?well i bought the car 3 weeks ago after a week the brake was not wrking properly.

and sorry i didnt get u what do you mean it could be servo?what is servo?

the car is over 10 years old so compents in the brake system will be worn. if there is dirt in the fluid there 2 things to be worred about.
1) the seals and the barrel in the master cylinder i'm sure are damaged. so that will need to be replaced.
2) where the dirt came from. the brake system is sealed so out side dirt cant get in. what kind of dirt is it?? rubbery? plain muck? steel fillings??

the servo is the big round thing that the master clyinder is bolted to.

when i tryed to did bleeding the left front brake nothing was comming out i removed completely he bleeding bolt still didnt came out then i tried to pump the brake lots of time in the end i did push the padel very hard then the brake oil came out it looked like it was blocked and i say like sum sticky and dirt in the brake oil which was comming from caliper.after bleeding i put the tire back but still the brake was same.when i drive the car if i do one time brake he padel goes inside when i to twice pump the brake then the car stops but the padel goes down slowly.do you think if i flush out all the padel and put new brake oil will it work good?

it might but i'd be nervous of something if its that blocked. there is massive pressure in the pipes and if its bolcked there is something wrong somewhere.
if itwas my car i'd but the car on 4 axle stands, take out the master clyinder, open the ends of all of the pipes at the wheels and flush them out. i'd replace the master cylinder with a brand new one and new brake fliud.
i'd consider changing the slave cylinder in the rear drums and the getting new capilper up front. brakes are to important to be messing about with!!

there is a small pipe which is going from mastercylinder to the engine that pipe is bust do you think this can be the problem if i change that hose pipe.

is it from the master cylinder or the servo?? i tink you will find its from the servo. answer is yes to your question anyway. the servo works from the vac created in the inlet manifold. that will solve your having to pump the pedal problem.
that doesnt solve the problem of dirt in the pipes.

if your still not sure what the servo is i can put up a pic of one.

the pice was from the boster which goes in the engine i think vacume well i change the pipe its gone little better but still when i put my foot on the brake paddel its still going down slowly.can you tell me how to check the boster that its working or not.i tryed to poen the master cylinder but i cant open the bolts its very rusty and dont know how to open.

what do you mean by boster??

this is a servo, master clyinder bolts onto it. see the green plug?? the pipe from the inlet manifold or somewhere should go in there.
the master cylinder is a sealed unit so there's no point in trying to take it apart. in one of your earlier posts you talked about a piipe being blocked and there being dirt in the system. if this is the case until you sort that your brakes arent going to be great!!
drain the entire system like i said in one of my previous posts. flush each pipe through. if that doesnt fix it you my change the master cylinder.
how many miles are on the car??

the picture you send me the black round thing we call that brake boster.well i checked the brake when i push the brake padle fast it goes hard and brake work good but when i push the padel slowly it goes completly in.i flush all the lines and one thing is left i cant open the brake line from the mastercylinder cuz the bolt are jamed and rusted. i tried to open the bolt are sliped.i think i dont have anyotherway now to give the car to the mechanic.or there is a way to open it ?...lol

didnt know thats what you called it!
vice grip!!
to be honest of the pedal is going to the floor its either something wrong with your servo (boster) or the master cylinder so you might need to change them. the diapham in the servo might be gone or the seals in the master cylinder are gone. you might be as well bringing it to a mechanic if there is things that are going to be hard to open because then its his nigtmare not yours!!! lol!

Thanks for ur help Very Happy

i like to know if there is a air in the line will it do same thing?i did bleeding one left front caliper and 2 rear calipers i tryed to take out the air from the right side caliper but i brake the bolt which is for the bleeding:D do you think this can be the problem?dam man this shit brake thing is very confusing ..lol

thats what we're here for! Smile

yes that would also affect it. you may find a way of bleeding the 4th wheel.
