Question about 1991 Toyota MR2
How do i change my front brakes and disks on my mr2 1991 please help
Chock the vehicles rear wheels and loosen the front wheel nuts, jack it up and put it on chassis stands....
Remove the front wheels and then turn which ever wheel that you start with, into the direction of most convenience.....You will see that there are two bolts which are visible, and allow the sliding part of the caliper to do just that, so that the piston fitted to the inside unit presses outwards, and in turn, compresses the outer part of the caliper, so that the pads are squeezed on either side of the disc.....These two bolts DO NOT need to be removed for the job you are doing....
With your hand, feel lower down on the inside of the housing, untill you contact two larger 17mm bolts....These should be removed.....
.....Once freed of the two bolts, you'll be able to pull the caliper towards you and loosen the pads enough to lift off the whole caliper.....
......Have a piece of wire, that you can hang the caliper onto, and then hook the other end onto a convenient place.....(the suspension spring is a good place).....
.....Once removed you'll see that the disc is held by either one or two counter sunk screws....remove them and the disc can be removed....
....Replace the parts that you wanted to, and then reassemble....
When the vehicle is lowered onto its wheels, get inside and PUMP the brake pedal, four or five times....You'll have had no need to open the brake fluid lines, and therefore, no need to bleed the brakes.....Once the job is completed, they should feel higher and firmer than when you began....
Once you're happy with the 'feel' of the brakes.....happy motoring.....

One thing you will want to know...The rotors are usually press mounted to the hub. If these are the factory rotors you will see 2 small holes drilled and tapped near the center of the rotors. The easiest way to take them off is to get 2 bolts...8mm x 1.25. These will thread into the 2 drilled and tapped holes in the rotors. These are called push bolts.
Once you get your wheels off and your calipers pulled back and supported you will need to slowly thread them into these holes and do it evenly so that the rotor doesn't bind on your hub. This will pop those rotors right off without having to resort to a hammer or blowtorch to get them off.
If yourrotors have already been replaced, you may not have the luxury of the factory push holes, so a blowtorch around the hub and lugs will work nicely...always use penetrating oil around the hub and lugs before starting any work or replacing your rotors...this will help free them from rust and corrosion that might be causing them to stick.
I just did mine about 3 weeks ago and I wish someone would have told me earlier abou those push bolts. Good Luck!
