I am going to do a brake pad and rotor replacement on my 05- s type 3.0.

On the rears which way do you turn the calipers to re-seed them. I would assume one side is clockwise and the other is counter clockwise. I will bet the left is counter, but want to check and make sure before i make a mess.

Thanks

If they are like any of the other rear calipers I've done which is alot its clockwise on both sides. Cause when you look at it it will be the same. Its lefty loosy-right tighty. They are just threaded onto a post inside there nothing to fancy.

 

Do you have an electronic hand brake? I think they came in durind 2003 model year?If so I think you need a diagnostic tool to retract the caliper piston which have some form of electric motor in the assembly. They can't be done usng the conventional wind back tools. They will damage the caliper.

 

I was just reading an old thread about this but it may only apply to the STR cars with the rear brembos. I suggest some searching on "brake pads". It was covered pretty extensively and a bit harshly by one of the Jag Techs. It's probably worth your reading.

Jeff (JOsworth) did a pretty nice write up with pics showing how to do a 3.0 S Types brake job. Heres the link https://www.jaguarforums.com/forum/s...Osworth+brakes

 

Does anyone who has done this know what Carfax is speaking about? Yes, I have EPB, but in reading the site there was no mention of using a special tool, except from one of the 18 or 11 piece tool kits that I was going to buy and that was intended to wind the piston back in, before putting the caliper back on. (perhaps that is what you mean by retracting). I have huge common sense about cars, but they are not my field and so the terminology is not part of me.

My original question about piston on the rear calipers is that somewhere on the forum (I can't seem to find it again) there was mention of someone tearing up the caliper by turning it the wrong direction and some had mentioned that you clock them in different directions- depending on the side. Information and preparation before I start always helps my common sense side.

Thanks to all

Not true at all. The JTIS confirms that the pistons are to be retracted using a windback tool. I used a slightly modified cars parts store one-size-fits-all piece. Worked great.

The only 'challenging' part about the job is making sure the p-brake is released prior to starting the job, and re-calibrating the p-brake after completion. Those two tasks are pretty simple if the instructions are followed.

I don't recall which way the pistons are to be rotated and don't like to give out 'guesses'.

 

Leaving aside the STR (which has a separate EPB caliper) and sticking to the 2002.5MY cars (i.e. the ones with EPB), I am unsure how far the EPB retracts the mating face of the pad when off. Not far, I suspect.

However, I think the EPB module "knows" the position of the brake cable it controls (i.e. knows how far the pad has moved).

If you then change the pads and of course retract the caliper piston, the EPB module is out of step.

And that is (I think) why you should recalibrate the EPB after changing discs (rotors) and/or pads.

The details are on this site (I think - or the .co.uk one if not).

I don't believe there's any need to use a specialist (dealer) tool to control a correctly functioning EPB module, although it would also serve to recalibrate it I suspect.

 

I know it's about Brembos but "realtech" and others go into some details about how you can deal with the emergency brake release issue.

I hope it's relevant and helps.

alldatadiy shows that you rotate the piston clockwise to retract into caliper. No special tool is used to disable the EPB (read your owners manual). Besure to reset the EPB BEFORE engaging the vehicle into any gear (again in the owners manual)!

Does that answer your questions?

 

Hi, It's Me....

OK, that was bad....

The non-R car is real easy to do brakes on. The comments here about simply winding the rear calipers in is dead on. You can also "get away" with just pumping up the brakes when you are done and then starting the car.. That's what I did way back when I did the brakes and the Parking Brake has worked fine since.. BUUUTTTT... I wouldn't do that now.

I think a user by the name of "Norri" posted instructions on how to hand wind the parking brake after doing a brake job. I printed it out and am at work(lunch time!) so I'm not sure. I just know I won't skip that step again.

 

Hi Jazzwm.
Did my rear brakes about a year ago now and found it straight forward. I did buy a special Brake Cylinder Wind Back Tool, which made the job much easier to do. With regard to the EHB I found it worked perfectly okay after changing the Discs(Rotors in your part of the world) and Pads as it did not need re-calibrating after the repair. However when repairs are completed and to make sure the Handbrake is not binding at all, test the car on a gentle incline and see that it rolls freely forward when the Handbrake is released, with if an auto, selecting the gear lever to neutral position. I have a manual gearbox so not a problem in that respect. One point I'm not sure of is the Handbrake setup on the Automatic cars with the automatic Handbrake release, so it maybe a little different to the manual version I have.
When winding the Brake Cylinders back have good sized cloth under the Master Cylinder to catch any Brake Fluid that may be pushed out of the filling cap area. Mine was okay, but just be careful of this as brake fluid can damage your paintwork!!!
Hope all goes well with the brake overhaul.
