View Full Version : DIY Brake Pad Install Issue

Hey guys I started the front brakes tonight in prep for a F&R brake pad and rotor change on my 00 TJ wagon.
Got the front jacked up wheels off up on stands and got the old rotors out and pads fell out, wound the piston back in with a clamp and got my new bendix rotors on and pads ready in the monting bracket but when i attempted to slip the caliper over the pads and inside the mounting bracket I've run into the same issue on both sides..
Do the pads just sit in there (do you guys use anti squeel paste on the back of the pads?) when I went to push the caliper back down the clips on the pads pushed out the clip that was clipped in to the caliper... are the pads clips suppose to clip into/over the clip thats located on the inside of the caliper?? :nuts:
Now I'm kinda confused how the pads are supposed to be clipped in to the caliper at all???
Done a search for a DIY thread, but couldnt seem to find any info :(

4 and 5 clip onto the back of the pads.
3 clip onto the caliper.
No need to use goop if you use the shims.

gday max
nah mate my pads look totally different

bit hard to see in that example i found on the net as its so dirty (but see the little clip in the opening of the caliper)

You sure the pic of the pad is a front pad? It's been a while since I did mine but that looks like a rear one to me.

haha yeah i was thinking that after i posted it oops!
The front pads have a similiar clip, which i was trying to show madmax what i mean how the clips are totally different to what he posted up :)
obviously there are some variances between year models?

If I remember correctly, and as I said it's been a while, the spring thing is just an anti-vibration thing, not a clip. It just pushes against the caliper bracket when the caliper is lowered into position. Mine's also missing the shims, I used the paste stuff and there's no squeal but there is a bit of a clunk braking in reverse as there's a little bit of play. Next time I'll find a brand with the shims or I think they are available separately.

The "H" shaped clip is jammed into the caliper, if it drops out, try bending the legs of the "H" a bit so it sits in solid.
The springy bit on the pads themselves look like the letter "M" and the ends point down. The tops of the "M" can be a pain to get right, both need to be inside the caliper.
Some model runs of the Magna were fitted with any one of two makes of calipers - PBR, Sumitomo.
The rear same idea, as well as the wagon and sedans being different.
As above, it's been a while since I did my TJ sedan and TL wagon - but I think the picture I put up is for the more common PBR caliper.
The front pads of my 2001 TJ are definitely of the type in the picture I put up.
No shims on the caliper type you have, so it doesn't hurt to put some goop on, but not essential.****
EDIT: Just checked the old pads off the front of my TL wagon, they are the type you have and not the picture I put up. The old pads have two shims for each pad, but I didn't reuse them as the new pads had a layer of soft material on the backing to act as anti squeal material.
So I'd say you may want to use goop.
I usually take a pad off and take it with me when I buy brake pads, just to be sure. lol
(Anyone, feel free to update or correct the above info.)

In your picture of your caliper above you can see the shiny lines on the stainless steel shim thing where the springs press.

cheers guys
yeah the first time i tried to slide the caliper down the clip (anti rattle spring?) popped up through the hole in the caliper, this had me thinking do i need to clip these pads in somehow...
it was getting dark and i couldnt quite see properly with a torch, and thought bugger it i'll do some research on the net 2nite and tackle it in the morning when i can see and have more of an idea what these bloody clips are...
My supra brakes done on my last car were easy, the pads had two pins that slid into place to hold the pad..
Madmax, my caliper was a PBR FYI :) (on the front at least havent got to the rears yet!)
bendix pads were buy one get one free deal from SCA 2 years ago! ($70 for the pair by memory)

so the springs on the pads just press up against that clip in the caliper?

Up against the top of the inside of caliper, definitely. Possibly on the clip, not sure.

Yeah, pretty sure. You can see the marks on the steel clip thing where they've been pressing. The clip is supposed to provide a bit of slipperiness so the springs can slide a bit as the pads wear. As Max said you might need to rotate the spring so it doesn't pop through the hole in the caliper when it's lowered into position.

As an aside:
Don't forget to regrease the caliper slide pins with the proper stuff.
SCA sells satchels of bendix synthetic ceramic grease (its blue and $2.20 for 6 grams).
Don't use an oil based grease!

Ahh damn already got the front wheels back on :(
Now im stuck trying to get the rear rotor off. Obviously it's the hand brake shoes, I'm trying to find the adjustment, all I could see was a cog at 6 o'clock position, do u use a flate bladed screwdriver to push it up or down? Can't see shit when I tried to know if its even moving...
Should have just got the mechanic to do it!!! Can't look at workshop manual as I have that on my laptop which has a cracked screen, and I'm on my phone ATM...

Manual says "If removal of the brake disc is difficult, release the shoe adjuster star wheel (the cog) to a point where the brake disc is able to be removed by rotating the disc and pulling gently." Also says not to force it or the shoe hold-down clip will be damaged. The direction to turn the wheel depends on which side of the car and whether it's a sedan or a wagon. On sedans, passenger side, cog goes up to loosen, drivers side cog goes down. Reverse this for wagons.

And yes, flat bladed screwdriver through the hole in the disc hub is the tool of choice.

Thanks mate! I gave up on my drivers side, went to passenger side and chucked a tanty and pulled it off with my hands. When I went to put the rotor back on it was tight, worked out pushing the cog upwards around two turns allowed the rotor to be put on. Got that side sorted, tried the same on drivers side but it won't come off and I can't see a bloody cog on that side (is there only one on passenger side?)

Oh and I have a tj wagon, so yeah that doesn't seem right as my passenger side I pushed the cog up in the direction of the roof of the car?

There is a cog on both sides, should be accessible from a hole in the disc hub (ie. wheel side, not car side) so you might have to rotate the disc to align the hole over the cog. On wagons the cog should be at the bottom and slightly towards the front of the car by the look of the diagram. The directions on the image are to expand the brakes, so should be reverse to retract.

Yes that's definitely correct their at the bottom on the wagon! I eventually used two screwdrivers to lever the rotor off. On my tj wagon I adjusted the cog once the rotor was off on the driver's side downwards to slip the new rotor on (couldn't see nothing of the cog on the driver's side with the rotor on!) And upwards on the passenger side. Ahh well I've finally done it, but at least I know how to change the brakes on a magna now (I'll most likely sell the car before I replace the brakes again!)

I just bedded in the new rotors and pads, doing 10 brakes from 60 km/h (not coming to a complete stop) then 6 or so heavy brakes from 70-80 km/h (not coming to a stop) then driving 5 mins home to cool the brakes. I could smell the brakes bedding in, reminded of the scent you get when a train pulls up at the train station!
Looks like the rotors got some heat into them!

Heh, that suggests the manual has it wrong, or their use of "L.H" and "R.H" is different to how I would interpret it. Oh well, good to know.

The handbrake shoes almost looked worn out to me? Very smooth?

The brakes are tiny on these cars, here's my caliper off my 1500kg Bmw for comparison

Yeah who knows!! I just thought I would post a reply in case someone came across this thread in future, if they have a wagon with one brakes follow my instructions :)

Those handbrake shoes look just fine.
They will never wear out if you use them normally, ie stop car, handbrake on.
The caliper on the Magna is tiny, but so are the standard tyres. They are good enough to get the wheels near lockup so the ABS cuts in, but if you go to wider tyres a brake upgrade is a good idea.
I imagine the BMW has wider tyres than the Magna as standard, and have bigger calipers to reduce fade for those top speed runs on the Euro autobahns?

Yea that's true, i upgraded to 235/45 17" tyres, was a great upgrade!
Yeah the BMW has really good brakes, with supreme stopping power and can repeat hard brakes without fade with nice big x drilled rotors also
