Okay brakes questions, asked this before, searched, and found out what to do next etc, etc. but I still seem to have very very soft brakes in my 521.

 

Last night I adjusted the last pair of shoes, reatatched the drum, bolted on the rim, bled the brakes again (hmmm 7th time? :angry: ) and let her down. The pedal still has no feeling and or resistance and goes to the floor. if you pump the pedal up you could maybe get a little more feeling in it.

 

I have:

 

Bled the brakes 7 times.

Replaced the rear wheel cylinders (Seized)

Adjusted all the shoes. (As You've instructed)

Replaced the Pass Front Shoe Adjuster (Seized)

 

I have been able to get between 0% - 20% braking out of this thing :unsure:

 

So I am thinking tonight I swap in the new Master Cylinder? or is there something i'm missing?

 

Thanks Ratsuners

You adjusted the shoes with the star wheel....after the drum is on.....?....correct?

The star wheel is turned until the shoes touch the drum.....then slightly backed off.

Pump pedal 4 or 5 times, hold pedal to floor, open bleeder nipple.....close bleeder nipple.

Repeat till you have a nice stream of fluid coming out with no air bubbles

Here's a idea, don't keep calling it a nipple, I think his are becoming chaffed from squeezing them....no radio not those nipples, the ones on the back of the brake drums....ps 521 brakes wont ever be what your used to.. even when properly adjusted the rears will lock up like a e brake under hard braking.. yes you can adjust some of that out but over all braking will be sacrificed...I like where mine are at now stops good..but if i gotta get on them real hard i get loose...actually stopped phenominally when i had a quad in the back... but im not that guy who will drive around with a atv in the back of there truck constantly..this is the result of a single resevoir master... you can put a proportioning valve in but i would wait till you went discs and a z master cylinder

 

i have developed this wierd pulse on braking .... with out discs...i will pull the drums off and chack next time i adjust them...

 

one more thing, u will have to check you adjustment every couple of month's(under daily use) radio....they get out of adjustment..they probably didnt tell you that in oil change school...

 

ok last thing... i think if its between 0-20% you have a much bigger problem... go with "little ram" start with a new master cylinder..especially if he got you one.....and should you even be road testing something that has between 0-20% braking...

jrock, i daily drove the thing for like 4 months on almost no brakes.. seriousley had to pump 7 or 8 times before you had ANYTHING. i got used to it and it was all fine so i never fixed it. i could stop as fast as i needed to, never really took it out of town or on the highway, and was always a slow driver in it i took it all the way to canadian border. think it was like 220 miles or some shit and it made it just fine. also took it on another 600 mile trip over the summer that was fun! so if you are experienced, and TRUST your car, you can drive it. not saying i trust radio driving it, but i do trust my self very much driving it. i also agree with jrock radio, dont test drive till you get complete brakes, or almost complete.

thats a funny story.. i will drive my datto for a couple of weeks then jump in my tahoe(automatic)riding with my wife i was coming to a stop light and stepped on the brake pedal like it was the clutch .. locked them up and put my wife on the dash, she was so pissed(thanks dtp) ...everyone was starring at the tool that just locked up his brakes 100 feet from another car...all i could do was laugh... oh and apologize...i get what your saying about learning the nuances of certain vehicles you drive...trust me i got lots of rigs and they all require different driving styles...personally I think radio should keep it real and put the husky wrench down....its almost like this 65 pages is one passive aggressive joke being played on the minds of datsun people everywhere...were united and if you read some of this stuff ... it just seems surreal...and not in a good way....i think this thread should be locked... i been sensored on here for bringing up valid points yet radio can make some helmet wearing statement and get a way with it... its like hes got naked pics of the moderators and a sheep or something...i get told i am not being productive or bringing anything constructinve to the table in this thread but there's probably 45 pages of non or misimformation in this thread...i love ratsun and the epople on here.. much more friendly then the realm or other datto sites...but this is ridiculous...i know i dont have to look...but seriously can you look away from a car crash aS you drive by...the pics of a wrench sitting on a table... or a quart of oil with the lid off is wasting bandwidth...sorry if this seems harsh but I just think any newb coming on here and seeing this may be discouraged from yusing ratsun...i mean if you just got a datto came on hare and seen a pic of a dude in a orange jump suit holding a standard wrench getting ready to use it on a foriegn car wouldn't you be discouraged from taking this site seriously...I know this is a hater mentallity but seriously guys every and i mean every question in this thread is redundant and with a search could have been answered...I got real problems...like a crappy economy, high blood pressure, struggling to survive ... a datto with a mystery electrical gremlin .. read( starting new techincal thread after exhausting my search) not a picture of a thermometer... stating in winter it's cold...and seven other photpo graphs of hitchi carbs on a shelf...if you want pictures of arcaic shit, let me start a thread entittled shit that dont work, will never work and yet i will never bring myslef to throw it away... no crap... and when i touch fire its hot...anyway read it quick...it could dissapear along with its merit and understanability...or maybe radio will now call me a hill billy cause some how he thinks my avatar represents that i am a hill billy...and i have no idea...or clue what i am doing... no sometimes i dont but my friends of ratsun, help guide, diagnose and educate me so i can help others and or increase my knowledge base... this site is beyond helpful and populated with some of the most knowledgable car people i have ever dealt with...sure know and again you will get razed for something but thats what family does.... help, stand behind and sometimes ground each other with a well timed zinger...WEll ram i think i covered it...sorry for the eyestrain and populating this thread with non information but i gotta go ask a dumb open ended question in hopes some fellow ratsuner has runinto what i have going with my truck...its funny im on a lot of forums and everyone has something like this... and i should a known after downshifter took off and sold that crooked air bagged 620 that it was only a matter of time till he was replaced...

I had a similar problem with my brakes, bled and adjusted them a million times and they were still too soft. If you haven't already (I'm not going to sift through this gigantic thread to check)you should bench bleed your master cylinder. If an air bubble is caught in there it will often not bleed through the brake lines. You can do this yourself by removing it and putting it in a vice, and then bleed it through the nipples (lol)that are on the master cylinder. Use a piece of wood or metal for leverage when pushing and holding. Or if you have a buddy to actuate it you can bleed it while its still on the truck. Or a new Master would work, just make sure you bleed that one too!
