bleeding car!

[masterb]

After replacing my damaged brake line, and flaring my new lines with my e bay 10 quid tool!

i am now ready to bleed the system, i am just doing a quick post to see if anyone could offer any advice to doing this.

The front end should be relatively easy, its the back of the car i am slightly worried about.
havent had a look yet, but, where are the bleed nipples on the back.
I am guessing they are going to be a bugger to find and work on, what with those silly inboard brakes.

Any help would be greatfully received.
Ta,

those silly inboard brakes are actually quite a design benefit, as they reduce the unsprung load at the end of the drive shafts , improving the ride ,


as for bleeding, it should be done,
front right,
front left
back right
back left

the bleed nipples are on the rear callipers, and can be a bugger to release for bleeding, and have been known to snap off if a proper brake bleed nipple spanner isnt used , this is a special spanner , like a ring spanner but with a slot cut into the ring to allow it to go over the pipe

good quality DOT4 brake fluid will be fine ,

dont let the reservoir run dry or you will pull bubbles into the system and you will have to bleed they all the way out

bleeding can be done with the engine off , no need for servo assist for bleeding

thanks very much bb,
i can see you must be a fan of the inboard brakes, but i am not entirely convinced they are so great.
My main reasoning being that if it was such a good idea, all the other manufacturers would have done it, and also would be using it today.
Also i am a bit put off the inboard idea, as it makes working and servicing a real bugger.
I think i might be taking the angle grinder to a ring spanner in order to carry out the operation tomorow if that sort of toolage helps.

i am pleased to here though that there is; or may be some advantage gained from the inboard brakes.

Ta 4 your post again.
p.s. am i right in assuming that later facelift xjs's hahe there brakes in the normal place? or did i imagine that.

I am not convinced you need to cut a slot in a good ring spanner.

After all if you place it over the nipple and release it you can then place the bleed pipe over the nipple end, bleed the caliper and tighten the nipple, leaving the spanner in place.

If you require more room, release the nipple with a ring spanner, bleed caliper and use an open ended spanner to close it.
It does not need to be overtightened.

Your Quite right there Kels,

Did the job at the weekend, there is no pipe/line going into the bleed nipple so as you said you dont need to butcher your ring spanners.

However i am sticking to my original prognosis as far as inboard brakes are concerned they are a sh1t idea.

What a bugger of a job, back wheels up on my ramps, lying on my back, with a ever increasing crick in my neck.

This would be just about tolerable, but then when i try to get a spanner or any type of tool near the bleed nipples, i find that the exhaust pipes are so close that i cant get a tool on!!!
Well eventually i just about managed to come to a solution, with a few grazed knuckles.
Give me brakes on the wheel hubs any day please.
I have a set of redstuff pads that can go on the car, but i am more than a bit reluctant to do that job, after this experience.

4 got 2 mention,

interestingly the jaguar manual suggests you bleed the car in a different order to how you would normally do a car.

Cant remember the exact details, but it suggest you do the rear right first, then rear left and the go to the front.

To be honest it seems to make sense to me, that you do the rears first, with the longest run of line.

I would disagree that inboard brakes are a bad idea.

They are a good idea implemented badly!

What the inboard brakes really need is an access hatch under the rear seats, a la old Triumphs, but I sure as hell was not going to cut one! (Without the rear subframe there is not alot of car there and any hole I thought would weaken it badly.)

As a footnote, I have owned both a 3.6 (inboard) and my current 4.0 (outboard) and there is no discernable difference in handling.

Sorry iain, but there is going to be no convincing me they are a good idea.
Particularly after reading this
(As a footnote, I have owned both a 3.6 (inboard) and my current 4.0 (outboard) and there is no discernable difference in handling. )

From your post, which doesnt surprise me in the least that you cant feel any difference or advantage/disadvantage.

In fact your post really cheered me up hearing that footnote. i wonder if i can stick a later 4ltr back end on,?

Im going to stick to my guns on this and say that if inboard brakes where/ are so good, all cars would have them.
An access point seems good 4 sure.
