Good morning

My car (1994 6.0 convertible) has been through a lot of preventative and required maintenance including new coolign system, ignition system, brake discs, pads and parking brake shoes, exhaust, subframe mountings etc.

The car is still in the workshop (not a Jaguar specialist because there isn't one, but very well known to me) and a couple of issues are holding its release back:
The ABS light is on as is the washer fluid level warning light.
The parking brake is not holding the car.
When the brake pedal is pressed a yellow warning lamp illuminates in the display.
The low washer warning light is illuminated yet the fluid is full.
The ABS warning light is on continuously.

I am assuming that codes for the ABS can be pulled from the boot / trunk as in earlier vehicles. I have also searched and pulled some ABS Diagnostics and Blink Lights pdfs that I found on other posts on this forum, although I think they apply to pre-facelift vehicles. I have also read that the ABS accumulator can be problematic.

Are there any other suggestions please?

Best wishes,

Pierre

 

If your car is similar to pre-facelift cars, IF, repeat if, the handbrake is engaged (which means in this context that the handbrake microswitch is in the position it should be in when the handbrake is applied) AND then you press the footbrake, the yellow warning light should illuminate. This is to test the circuit and is a feature of the car.
Therefore, if this applies to your model, it would indicate that the handbrake micrsoswitch is badly adjusted. It can be found under a cover over the fulcrum of the handbrake lever.
I take it you understand the correct way to apply and release the handbrake?
As to the handbrake not working well: does your car have outboard or inboard brakes? If outboard, then it is just a matter of following the mechanism's action from the cable end at the axle to the mini brake shoes inside the discs and suitably adjusting either the cable or whatever needs it. The cable length is adjusted by a threaded mechanism just rearwards of the Driver's seat set under the carpet covering the inner sill. I expect, but do not know, that the brake shoes will have an adjustment mechanism too.
If you have inboard brakes, post again.

 

Thanks Greg. Much appreciated.

I’m conscious that I haven’t given you feedback on the exhaust system but the car remains in the workshop. Once I can I will....

 

First thing I would look for is loose or corroded connections everywhere along the wires for the washer fluid and brake.
The parking brake micro-switch connections under the plastic handle-cover and notorious for coming undone.
It's stupidly hard to get to since there are few Phillips screwdrivers that are 1 inch long.
The parking brake on my 94 never was very good either but I rarely rely on one so never tried to fix it.
I don't remember having an accumulator on my 94 coupes but they may have added or deleted it in the versions.

 

 

They might work, unless the item dimensions stated are correct.
I'll assume they meant MM.

 

Thanks for all replies.

the ABS issue is resolved and was due to wiring to the rear left wheel sensor.

the parking brake issue remains currently as does the washer fluid level light.

 

Do you have inboard or outboard rear brakes, please, as this greatly affects the parking brake advice.

 

They are outboard Greg. Possibly the microswitch.

 

Pierre,

The brake shoe adjustment for the handbrake is fairly easy.

Ensure front of car is properly chocked
Raise the rear of the car (both wheels at the same time)
Remove the wheels
Put car in Neutral.
Release handbrake
Turn the rear drums until adjuster access hole in drum is at about 6 o'clock. From memory, it's not quite dead centre and you really need a torch to see the adjuster pawl inside to get the hole exactly right.
Insert a screwdriver and push the toothed adjuster around to get the handbrake shoes to engage the drum. Check by turning drum. It can be quite fiddly to turn the adjuster.
Once happy, back off the adjuster just a fraction so the drum isn't dragging.
Repeat for other side.

Now see if the handbrake works. It should lock the wheels after 2 clicks.
If the handbrake now doesn't work properly, it's probably a cable adjustment issue. See if the handbrake is locking one side or if it just isn't working.

Good luck

Paul
