Rear caliper bleeding

not sure, if I like the rear brake system...
Former owner spent a lot of money for overhauling the brake system (new booster, one rear caliper new, one overhauled, all the handbrake levers new, etc) but I had to change the main brake cylinder. So, I looked for the bleed nipple on the rear side. From the WSM I know, it´s on the LH side rear caliper.
Jacked up the rear of the car in my garage and secured everything. I do not like working under the car with the DeDion tube right over my nose. From under the car you cannot see the bleed nipple, finally I could feel it, it´s more on the rear/top side of the caliper. I could try to drive to the workshop like this, but .....
Is there any trick with this work, using a mirror or whatever or am I completely wrong ?
 
I understand what you say about the DeDion tube over your nose, i felt the same with the tube over my chest or throat while removing / refitting the rear calipers in the past. Anyway, you don't have to do the same to reach the rear bleed nipple. You can reach it from the back of the car, without having to lie on your back. There is no need to actually see the nipple, just lying on your side under the boot floor and extending you hands over the DeDion tube will be enough.
 
I tried to get a "Kwik-Lift" (US) here but no chance. If you go on their website, you can see, it would make most of the work easier and more safely. Thanks Demetris, I will try it this afternoon. Just thought to cut a service opening from the rear seat body shell, no no, forget it...
 
I have seen pictures of Jags , all burnt out, as a result of trying to cut a hole in the boot to access the inboard rotors etc, so dont even think about it mate,
buy a hoist or dig a pit in the garage floor, better still, go to a Rover service center for the job....:eek:
 
No worry guys, was not a serious idea (if the tank is not above, it could be...). My garage has a sloping ground, so no base for a lift. To dig a pit in a home garage, you do not know what that means in Germany :confused:
Have made a drawing for a Kwik-Lift pendant, but in Germania we have "full labour rate" and you will definitely find no workshop which is welding those things for you. It´s a little bit crazy here.
A Rover Center, ähem, for that I am 25 years to late here. So, no chance, I have to do it
 
What you can do to make bleeding a hell of a lot easier is to remove bleed screw altogether and connect a measured length of goodridge hose to that point and then drill a hole into area behind boot trim/ in front of fuel tank and fit other end of pipe.
Into the pipe fit bleed nipple, can now bleed while sitting in boot.

Now that is a brilliant idea cobraboy, a remotely located bleed nipple..:) BTW, what is goodridge hose?

so it is a rubber hose like a brake flexible hose?
how would a bleed nipple fit into the hose, a picture would be so useful..

It would have a male and female end one to fit into bleed nipple union on caliper and one to accept bleed nipple. I don't have picture to hand but would look similar to rear flexi hose. One of the many hydraulic hose companies would probably be able to make one also.
 
I have bought a one way bleed nipple, useful because you don't have to keep opening and closing the bleed screw, and a joiner so I can connect a hose and the bleed nipple. I am going to fit these along with a spare hose I already have, the very next time that I take off a disc or anything under the back of the car, as it really is difficult to bleed those things! Whether I run it into the boot or just somewhere more convenient under the car, I don't know. But I can put the hose into the top hole of the caliper, and the transfer pipe into the botton hole to aid bleeding a bit. Then run the hose through a bracket like the front pipe on the upright, then into the joiner and the one way bleeder at the end.

What could possible go wrong ?:cool:

Nothing with a P6:oops:
 
never heard of a one way bleed nipple? how does it work?
just slacken off and keep pumping, then tighten when all air out of pipe?? o_O

It should be 3/8 UNF, or I hope it is, because I´ve ordered a 480 mm long brake tube (with male and female connector) plus one Speedbleeder, after I had realized last sunday, that it´s not a good idea to be under the car, close to the diff and loosening the bleed nipple. I´m doeing those work on one of those "flat trolleys" for mechanics. It´s ok, when you are moving under the car, but if your garage ground is sloping you should be prepared that these trolleys have no brakes. When I stopped under my Smart, I said, ok, go for Clive´s tip.
Before Richard informed about the Speedbleeder, I found a similar thing from stahlbus.com. Same principle, but as you may know from the Germans, a little bit overengineered but a real nice thing with a CNC machined cap available in all happy colours :). They also have nice quick-release drain-plug systems for sump-pans (engine, gearbox etc).
But, if speedbleeder or the Stahlbus thing, these oneway bleeders make life really easier and safer.
Demetris, the car stands (rear raised) on blocks on its tyres, so the DeDion tube is "up" and you have no access from the rear.

OK, i presumed that you had the rear left corner jacked up with the wheel hanging down, like i did.
If the weight is still on the wheels i understand that it is not the same.
