Dollywobbler's Maverick

[dollywobbler]

I'd better start a thread for this I guess.

Here's my 2.4i Maverick swb.

Today I started the servicing. While the oil was draining, and after discovering that I'd been sent the wrong spark plugs, I decided to investigate the horrific sounding brakes. Here's a small clue that all was not well.

What surprises me is that it's only in the last few miles that a grinding sound has been heard. I got caught out because a quick inspection when I had the tyres changed revealed only that the other pad had plenty of meat on it.

Unsurprisingly, the disc is knackered too.

This'll be why! Seized pistons in the brake caliper.

I'm trying to get my hands on a second-hand replacement, but have ordered new pads and discs.

With that trauma behind me, I set about changing the oil filter. Easy! Er, no. Most of you know about this, but for those that don't, here's the oil filter seen from above. It's that blue thing that's out of focus.

Access via the inner wheelarch isn't a whole lot better, but I was helped by the fact that the filter was seemingly only finger-tight... I hope I've done a better job of fitting the replacement.

I also dropped and replaced the coolant, though I couldn't flush it out as I'd hoped as my outside tap had frozen solid. It was bloody cold today. However, after successfully 'burping' the system, the heater seems better! Quite pleased about that.

Had to put the caliper back on the Mav so I could move it, albeit with handbrake only. To be continued...

Yep its cold out there today. Dont forget to read the download before you change the discs and pads. regards bri

Thanks. As with the other stuff I've already downloaded and digested, that's a very useful guide. Guess I should do the job properly and lube up the hubs while they're off.

what's up with the old calliper? I have had stuck sliders and with perseverance and some penetrating oil it can be fixed :thumb2

'edit' just read your caption to the above photo doh....

getting there. try ringing rose garages in tregaron, they may have one there scrap.

 

[dollywobbler]

Thanks Fez. I'll give 'em a try tomorrow. At least at the end of all this, I'll know what's what. And hopefully avoid any nasty surprises come MOT time...

while u got the tyre off chuck some grease on the stearing stops heard folks on hear saying about thudding noise on full lock and seams to be the solution to this
might not be a prob now but in couple of month after all that work u might be wishing u had done it

good thread keep up the good work:thumbs

nice job mate, bet it runs really well now.

Hi

Are you the same DOLLYWOBBLER from RetroRides/Autoshite Fame??

Im on there too

 

[dollywobbler]

Any idea how you differentiate between the two types of caliper on these? Apparently some have cut-outs for the hose locating lug, and the other type don't. I've no idea what I've got! Don't know if this pic helps.

 

[dollywobbler]

Sorted. It's the type the chap had in stock so it's now on its way, with discs and pads coming from somewhere else. Hope the weather's nice next week...

 

[dollywobbler]

Ugh. Unsurprisingly, the caliper sliders are borked. Managed to get one out with a bit of gentle persuasion, the other one required some rather firmer treatment! I lack a vice, so opted to try and remove the sliders on the car. Lots of penetrating oil, some 'back and forth' with a spanner (some taps with a hammer were needed to get it moving) and then hitting it with a chisel in the direction I wanted it to go eventually had the thing out. It took a LOT of walloping! No wonder the brakes weren't working properly...

Naturally, the rubber boots were a casualty, and the sliders themselves look dreadful, so I guess this job's on hold while I buy some more bits. Have caliper, pads and discs, so hopefully it won't be too long until it's all sorted!

When doing the Discs, there is quite a bit of work, no special tools but a 6mm AF allen Key in a 1/2" socket and a torque wrench won't go amiss, as the Auto-hub bolts can shear, as my local main stealer did, but failed to tell me until I took the wheel off some time later.... But that was 14 years ago when it was still under the 3 year warrenty.

You will also have to remove the wheel bearings, and the bearing nut is a great piece of engineering, held together with a small pozidrive screw, I think there is a down load on this. DON'T loose the screw...:doh

TIP: don't push the driveshaft inwards when re-assembling as it needs a gorilla to push it back in from the back so you can get the snap ring back on.... :doh Quite a few members would have no problem with this....:lol
I made that error, and it was quite a maul but dooable...


Think safety.... Axle stands all round, I even put the removed wheel under the chassis, with some blocks of wood to save damage to the rim, should it slip.

You are looking at a 2+ hour job each side, so why not grease the bearings, Auto Hubs, so read up on those tasks while you are waiting for the bits to arrive.

Get some copper slip ( Grease) for the pins, for the rear of the new pads.

 

[dollywobbler]

Thanks. I've been reading the download on the disc change with great interest. I was indeed planning on greasing up the hubs, though rain stops play now - that and the fact that I've failed to locate sliders and rubbers! (have now though)

Some great tips there though. I'll try not to repeat your mistakes! (but I don't make any promises...)

stuck sliders? looks like my advice wasn't so wrong after all :thumbs

If we put all our minds together we would be dangerous :lol:lol

 

[dollywobbler]

Indeed! Disc now off. That was a bit of a job! Separating disc and hub wasn't easy at all. They were keen friends! Inevitably, despite my best attempts, I was left with one 'thing' after removing the hub that left me thinking "where did you come from?" Now off to have a gander at the download on disc removal again to see if it has any clues...

Auto-hub is indeed looking a little low on grease so I'll be busy tomorrow even though my sliders won't arrive then.

I am a little concerned that the pistons in the LH caliper seem very 'rigid.' Should it be possible to push them back? Going to need them to go back a bit to get the new pads in.

If the pistons won't, you could pop them out, remove the fluid seals, and clean the inside of the bores. You'll need something bent to get in the groove that the seals come out of, so you can scrape all the crap out that collects in there. Don't scratch or damage the pistons, bores, or seals. You can reuse the seals if they're in good condition, but I would recommend replacing them.

What's the "spare" bit look like ?

 

[dollywobbler]

It's the locking washer according to the guide. Thought I was being really careful putting everything down in order but that somehow slipped through the net...

Where does it go in the order of things?

 

[11redrex]

The locking washer from the hub ?
