Little bit grumpy but rather more smiley. Twinkle (the Ibiza) and I collaborated over some of the service tasks for this year. She was registered in the March so her service regime (yearly or 12,000 miles - I don't do extended service intervals) fell due in the poor winter weather. I don't do a large annual mileage so when I took over the servicing when her warranty expired I time shifted it to the better summer weather. Her service warning has been reminding me for the last couple of weeks so, as the oil arrived yesterday I decided to make a start on it today.
I always do new oil and oil filter every year. Also the cabin filter - I've mentioned before that I like to ensure there's no restriction in the flow of air over the heater speed resistor pack and the Ibiza's pollen filter is an easy one to do. However the official recommendation for the air filter is every 2 years so I like to check it first before just going out and buying one. This is the grumpy bit. First, here's a picture of the filter casing:
To see the filter element you've got to remove the entire casing from the engine because it's held together with a whole load of torx screws which are only accessible from underneath! You can see 3 of the lugs these screws screw into along the front of the casing - there's another 3 on each side and one waiting to catch you out which "hides" right in the middle! Can't help wondering how long little torx heads will stay usable - if the one in the middle rounds out it'll be a real nightmare to do anything with. The first time I undertook to remove it I could see that there's a larger torx just to the left of centre which I undid but it still didn't want to come off. I eventually discovered it sits on 2 rubber grommets and you have to pull up quite violently to free it. Oh, and watch out for the big "super strong" spring clamps - you can see one on the intake duct front left and another on the feed to the turbo intake:
I use a pair of water pump pliers on them but these clamps are STRONG and if the pliers slip it can draw blood! Note to self, must buy the proper tool.
So to see if I needed the filter I had to do all the above and then, having decided I would do the filter, reassemble it and drive round to the factors (SRS) then back home by the "long route" to get the oil nice and hot for draining. Then, having done the oil and filter, I had to strip out the filter again to change it's element! I really can't see why the casing could not have been made with a removable top. There's nothing else in the service which requires the filter casing to be removed so It's not as if it has to be moved to give access to some other service part. Leaving the bulk of the casing in place would also reduce the chances of something being dropped down the turbo intake!
The rest of the engine service went without a hitch. By the way, I'm in the "prefill filter" camp - if it's the sort of filter you can prefil. Experience has convinced me that it considerably reduces the time the engine runs without oil pressure as it fills the filter. Ideally it works best with "hanging" filters and you can't do anything if it's a "standing" installation as all the oil runs out! But here's the thing, what about horizontal fit? Like the Ibiza and our FIRE engines. A lot of motors have horizontal fit filters. I've found that if you fill the filter about 3/4 full and then quickly lift it into place, only turning it on it's side at the last possible moment WHILST AT THE SAME TIME ROTATING IT AS YOU DO TO SCREW IT INTO PLACE then almost no oil runs out because it's running around the inside of the filter. This works because oil is a viscous fluid so doesn't flow so easily as, say, water, which would just run out!
So, engine work done we moved on to the brakes. She's now in her 7th year since manufacture and still on her original brakes. - mind you I've only done 30,000 miles in her. However the brakes generally, when you view them through the wheels, are looking "tired" so I decide to do a complete strip down and see what we've got before firing the "parts cannon"
I've said before how I'm not particularly impressed with this vehicle's front brakes - much preferring the type with a seperate removable caliper carrier bracket. However I have, at last, found something really rather good about this design. Once you've removed the caliper, which comes away by just removing the two slider pins, the disc rotors can then be removed without any further dismantling - very unusual?
So remove the wheel and caliper slider pins:
pull the caliper off, remove one small torx disc retaining screw, pull the disc rotor off and you've got this:
I've never taken a disc rotor off so quickly!
The hub flange itself is interesting. Look closely and you can see it's not one smooth surface as most others I've worked on. There's an outer and inner machined ring which contacts the inside face of the disc mounting area but between them, where the wheel stud threaded holes are, it's relieved so it doesn't touch the disk. This shows it in more detail:
I'm wondering if it's an attempt to make it more difficult to trap "foreign bodies" which would make the disc run out of true? Anyway, whatever, it was a very easy flange to clean up, especially after the last one - the Mazda - with it's wheel studs sticking out and getting in the way.
Now, with the discs and pads on the floor, it's time to make my mind up about what needs done. Well, the outside of the discs look pretty good, with just a small wear ridge round the outside and a wee bit in close to the hub:
The backs are a bit rougher, with a rust band on the outside and around the hub:
I often find the backside of discs are worse than the front So, if you're looking through your alloys at your discs don't assume the back of the disc will always look as good.
Next I measured the thickness and it came out half way between the new and worn out figure with loss of thickness being shared equally between the inside and outside faces.
Hmm? so, pads, what are the pads like:
Certainly not yet worn out. Probably about 75% worn, taking into account they will be changed when down to about 2mm. After cleaning it could be seen they were still mechanically sound with no cracks or separation from the backing. Let's give their faces a wee clean up then. What do you guys do about cleaning/glaze busting? Many years ago I was given a piece of thick plate glass by an "old hand" who told me it was especially good for this as it's very very flat. You put a piece of medium emery cloth on it and rub the face of the pad until it cleans up nicely:
Keeps the face of the pad nice and flat, which is what you want. I've had that piece of glass for over 40 years and it's moved house with me at least twice - how has it never got broken?
Well, so far I've not spent any money and the pads are looking good for many more miles. Hows about the discs though? They've got plenty of thickness left and the wear is even - I've had no juddering when braking. Lets clean them up and see what we've got. Fitted a medium abrasive disc to my electric drill and buffed a way the outside lips and inner rust on both sides of both discs:
Outsides came up pretty good:
Insides not quite so impressive:
Hmm? well, I've seen a lot worse. Think I'll just live with them for now. Get a bit more use out of the pads and then change the whole lot, maybe before it's MOT which is just after Christmas.
When reassembling it's worth knowing that the outer pad doesn't move in the caliper, simply sits against the fixed "fingers". But the inner pad is pushed along by the piston and must not bind in the caliper. Look at this:
The left pad simply sits there resting against the caliper casting but the right pad has to be able to slide freely on the caliper casting as the piston acts upon it. I've found that right pad (left pad if looking at the N/S) is prone to seizing in the caliper so give it a good "slaistering" of Cera tec or other brake grease when assembling. The Cera tec is the semi transparent, sort of toffee coloured grease, I've put a bit of white ceramic grease on the top slider just "boots and braces" in case.
Here's the end result on both front brakes:
That'll do me for a while anyway.
Looks much nicer through the alloys than it did a couple of hours ago:
Of course I'm in the fortunate position of being able to keep a regular informed check on this so will be able to quickly renew the discs and pads if they start to deteriorate more rapidly. In the workshop, I'd have been thinking, "Can I be sure these discs and pads will be OK for another year or so - or whatever the service regime on the car was" Extended service regimes make this very difficult. If the car was on extended I'd have recommended doing them now, at this service. If on a yearly/10.000 mile regime I'd be taking into account what I knew about the customer. An elderly driver who perhaps does a couple of thousand miles a year? I'd be happy to leave them, A "young blood", tearing round the lanes and "frightening the horses" I'd be doing now. It's all a matter of judgement and erring on the side of safety folks!
So that was it for today, except I popped the cabin filter in before I packed in for tea. Might get stuck into the rears tomorrow if the rain holds off. Not expecting the rears to be as good though, maybe going to have to spend some money on them.
