Stuck breaks

Ok car came off the road last sept for the winter and a respray, up till then breaks we're fine, however while at the painters he commented that over the two weeks he had it it was getting harder and harder to push around the workshop but I just put it down to surface rust or lack of use. However taken it for the mot today and noticed the breaks we're holding me back slightly, it passed but he said the breaks we're sticking but I know him we'll and said I'd strip the callipers as soon as I got home which I have done including removing and cleaning the main piston and the two sliders. Only thing I can find is the top slide pin which is slightly smaller than the bottom one is a bit stiffer than the other. Not sticking (you can move it in and out by hand ) but apart from that everything else is clean free and greased. Spun the wheel and fine till you press the break then it breaks but doesn't fully release. You can turn the wheel by hand when on axel stands but it's very hard to do. Any idea's folks?? Is there a valve or anything that can stick???

Forgot to mention all 4 are about the same

have you greased the slide pins to caliper brackets which bolt to the hub?

Yes bob, also the anti lock light is on the dash, but I can't see that causing any problems but could be wrong

I have a similar thing but with one caliper at the front  but havnt worked it out .... ive stripped my caliper down scrubbed it up its got brand new everything .... when up on axle stands i started it up all spin round fine other than that one catches as it spins slower it throws the abs light up ... took it for a spin and it doesnt throw the light up due to momentum of the car pushing it the same ...

Been speaking to a mechanic mate who says as it's all four and I've gone over all the callipers he thinks it's the master cylinder pushing breaks on but not returning so holding them on. I've left it half an hour and the wheels turn slightly now as if the pressure has slowly released. He said over the years break fluid and crap can build up on the seals and plunger in the master cylinder making it stick and as I think it's easy to exchange then that will be my 1st point of call. He said to test my servo by pumping breaks up hard then starting the car and if the pedal drops half an inch or so then that's working ok. Hopefully this thread will help someone else in the future.

Can't find one on ebay so release the Leighton wonder finder on it lol

Just spotted the other thread in general discussions , can't believe there that expensive

Yes mate they are a pretty penny ....im trying to find the thread  wich was saying about using it from another car ...

Been reading on modifiers and a couple talk about the Almera cdi

Ive read the almera N15 master cylinders fit, but still cant find any new copied ones, Looks like Nissan are the only source  

Ive spent a full day searching the net & ringing round & can not find a new 1 anywhere

Right just found this of a nivara... Ive got a GTiR master cylinder sat infront of me now & its identical, looks the same lengh & brake line ports are in the exact same place., Only thing that's different is the resivuar
Plus with it being of a navara its got to be the same size internal bore, if not bigger

Pulsar bore is 7/8 if that helps gaz

Pulsar is 15/16 from everything ive seen today & also got 15/16 stamped on the side of the 1 ive got infront of me Leighton

Or is 15/16 & 7/8 the same thing?    Im shit with maths so don't take the piss   

7/8 is slightly smaller but shouldn't make a difference as long as the internal length is the same or rod may be too short/long

Im going to ring him first thing in the morning & ask him to measure the length, if its the same then ill go down & get it as he's just round the corner from where I used to live

Oh right i read it was 7/8  ..... anyway hope it works out be intresting to see if its the same as im sure it will help alot of people out ...

Yup im hoping it works lol, Ay ill of found a new mod for the R that know 1 else has

Ahh that's abit cheaper , just trying to find some info on internal bore size but cant find anything   

Hold up il see what i can find out bud...

Is that bigger or smaller than standard internal bore? Think that's bigger so that's abonus

This will be so good if it's a goer.great work motorsporters
