About to change brake pads

[whitelandy33]

Anyone know where I can find info on changing brake pads for both front and rear?

I want to make sure I remove the calipers correctly. Looks like there are two thin bolts or screws that have springs attached to each caliper. Removing these... is that how the caliper comes off?

Thanks

sorry bad link to the write up. There was a article on his site about replace brake pads. there may also be something on the www.expeditionexchange.com website. and I think something on the www.discoweb.org both are in the respective sites "tech" section. good luck

Andrew,

I haven't done anything to my D90 yet outside of change the oil a couple of times, but if they are the same as my Disco 1 (which I changed at least 4 times since new) you do not need to remove the caliper. It's a fairly simple process and that article by Al Hang that Phillip posted is the exact guide that I used 4 years ago! Very helpful guide! You could get it done in less than an hour with basic tools.

Good luck!

Glenn :)

Appears the picture answered my question. I just need to remove the coter pins and pull bolts out. Slip new pads in.

Looks easy.

Thanks.

okay so I thought when you replace pads you were suppose to "turn" the rotors.. However, i didnt think you were supposed to turn Land Rover Rotors? Whats the deal just play it by eye?

Don't have the manual in front of me but there is a minimum thickness that the rotors have to be. It is normally listed on the rotor. It is good to have the rotors "turned" so there is no glazing but if they are not glazed too bad you can "scuff them" with emery cloth and you should be good. If the rotors don't look bad and you are only on your second set of brakes then I would just rub them with emery cloth, as it is a Royal PITA to pull the rotors off.

If i might ask.. what is required to take off the rotors, looks straight foreward to me and the other cars i have taken them off of seemed easy enough

This page on repacking or replacing the wheel bearings will give you a pretty good idea what you're in for when you want to replace the rotors:

'pretty straightforward. the biggest pain is cleaning and repacking the bearings.

If you buy the rotors at a dealer, they'll also recommend a kit of few other parts to get, such as replacement lockwashers, seals, and the paper gaskets. They're cheap and you should get new ones.

[Mike Hippert]

The rotors rust onto the hub in the rear and you have to beat them off, you also have to replace the bearings like Barry said. It is a PITA compared to the american cars that I have worked on where all you had to do was remove the caliper to get the rotor off.

How do I know if I need to do anyhting with the rotors?

I was just hoping to slip the pads in.

how many miles are on your truck? I think it is highly varible as to whether or not replace rotors. My thinking is it would be reflected by your driving style in addition to driving conditions? FWIW

95 D90 with 40k miles. Mainly street driving. Last time off roaded was year ago.

Most of the time I just drop the pads in. I have ~80K on mine and have only done the rotors once. As Mike says there's a minimum thickness listed in the manual, which I think is pretty conservative based on how often the dealer tells me on my two LR's that they need replacing. I replaced mine on the D90 when it was obvious they had gotten alot thinner, and the surface was worn pretty unevenly - at that point braking performance is reduced and the rotors cannot dissipate heat was well as they should.
