brakes broke, fixing. hope it runs again by 8am Monday
I assume disco's didnt come with hydro and you are kludging it together? That looks like a 90's chevy booster.
correct, and its the wrong master cylinder as I just found out
and I need one more 16mm o ring to -6 JIC adapter. Other than that its going smoothly. Fortunately I've got a junkyard line I can have crimped at the hydraulic shop tomorrow to get me going while I wait until monday to order the correct adapter from PSC (or not mess with it at all if it works)
may have to rotate it, stupid abs pump is in the way of the line fittings
the disco is slowly becoming a chevy :flipoff2:
yeah a little, but the transmission made it past 150k ;)
why?
had a bad brake booster and my newer used master cylinder started leaking in the same spot again.
Do I really need to justify any modification with this crowd?
They are gonna give you **** either way. :cool:

He is just showing the british how a 4x4xfar should be built
rover brakes are a little inadequate, especially with the larger tires. I could never lock them up if there wasn't ice on the road. So far I've probably got the same amount of money in it if I was to replace them or do this.Quote:

probably just has air in the booster, did you bleed it?
Even if all it needs is to be bled, I would still do the PS mods cause it makes the brakes work ALOT better. Pigpen's brakes kick major ass, I can lock em up at what I believe to be 40-50 mph (no speedo). But yes the booster takes awhile to bleed, I have done the one in pigpen when I built it and the one in my crewcab when I replaced it and it took awhile both times.
It just occured to me that the rover pump might be different than a regular saginaw type so what are your plans for boosting the pump up.
its a german copy of the tc saginaw pump. but I replaced it with a saginaw when the bearing went out.
what do you mean by bleed it? I was planning on pumping the brakes a few times and turning the wheel back and forth. Did you have to crack lines and stuff?
You need to jack the front end up and turn the wheels lock to lock about 20-30 times to get most of the air out, there will still be a little in there but it works its way out after about a week of normal driving
threw 2 washers in there, it doesn't whine at idle any more but it does when the brakes are applied or when steering. Is that what everyone elses did?
These brakes are amazing, even with the whine. This truck stops exactly how it should, but there is no power assist when its off. Is that nitrogen canister a consumable that need to be replaced?
Its most likely just air in the system causing the noise, but how'd you tee into the pump for the return? That canister just has a little spring in it (never needs recharging)
but the check valve may be bad. my brakes were never that bad...and they are really good on the LWB b/c of the hydro-pump they have for the ABS...which also make sthem work w/ the engine off...just gotta have the key on.
so how much for the hydro? I need to come take a look at all this...maybe I'll get my truck inspected and start driving it again :D you know where I cn get some disco seats?
Grayson there are no good disco seats to be found, especially if yours are manual. I kluged mine together using some parts off a power seat and swapping the passenger seat into the driver, but its still no where close to perfect.
Jeep seats are really close, I had a YJ seat bolted in, just have to drill a couple of holes. Bestop makes some nice ones.
price... too much
$40 at the junkyard, $60 for a new master
probably 250 for the rest of the chit from PSC, Brakequip, hydraulic shops, misc. brake lines that I redid.
I need one more 16mm adapter to get it perfect. I had to reuse the stock gearbox return line and a barb fitting to get it driveable, I couldn't find a -6 so I had to stack adapters and theres not enough clearance for them so the reservoir isn't in its final resting spot (the reason there are no pics :flipoff2: )
Mine had a remote reservoir setup from the factory. I wanted a filter and I needed a 2nd return fitting so I went with the PSC reservoir.Quote:

could just be a matter of how hard you could push on the brakes before, the booster just makes it easier to put the pressure on it you need to lock em up. Could you lock the brakes up before?

the power steering pressure has no impact on the amount of pressure in the brake system, thats like saying the vacuum pressure in a vacuum booster is making the seal leak.
The power steering pressure (or vacuum) does have an effect on braking pressure, how do you think the brakes are "boosted"? :confused2 Technically you are correct, the pressure from the PS does not directly affect the brakes. The booster assists you in applying pressure to the brakes, the more boost you have the more pressure you can apply.
Like was mentioned earlier, maybe you're pressing a lot harder than you realize now that you have the mega-boost. Or maybe it's just that crazy aloomineeum wagon you're drivin':laughing:
I think I'm pushing the pedal too much, might take some time to get used to not having to stand on the pedal anymore.
Brian heres my theory on whats being boosted.... the booster input rod and output rod do not move at a 1:1 ratio, is more like 1:1.5 I think the hydraulic or vacuum assist just makes up for that extra effort required to move. With no assist the brakes should still be capable of outputting the same pressure.
Might have something to do with burst rating and stuff I haven't studied yet, or I could be totally wrong.
Still growls when I hit the brakes... another odd thing is when the truck is off I still get one or 2 more pumps, but the pedal is much easier to press when the engine is off than when its running. Makes me think something is seriously f'd up. Its also spewing fluid out of the reservoir a little bit, but I do have a slightly pinched supply line to the pump. Waiting on a fitting in the mail to correct that.
I'm not necessarily talking about what part of the booster/mc is getting the pressure. I'm just saying that when you have more boost pressure (i.e. more PS pump pressure), for the same amount of pressure you apply to the brake pedal, you're going to get more pressure applied to the brake mc, which in turn applies more pressure to the hydraulics.
I might just be talking out of my ass though. :gigem:
couldn't find a 1/2" female NPT to 5/8" barb fitting anywhere to fix a kinked hose so started to crank one out at work but it started snowing. Left at 4 to avoid hazardous roadways.
I saw a disco today with all kinds of bolt on shat on it, my favorite, the "best 4x4xfar bumper sticker in the cargo area window....
Snow?
yeah, a little.
heres a bunch of douchy stickers

One thing I found with the noise, is that if the return is plumbed into the top of the reservior it tended to growl, but not when I used the bottom inlet. But you said you have a remote reservior.
and both are on the bottom if he is using the stock one
