How do you push in the rear disc brake piston on a nissan pintara far enough to get the new pads in.?

Question

Have tried using a g-clamp, but it will only move 2-3mm, had no trouble with the front brakes

Answer 1

use a c-clamp and leave the outter brake pad in place while you compress the piston into the caliper

Answer 2

I had a similar problem on a Honda. It was the parking brake set up. Look for the parking brake cable and see if it is on a ratcheting mechanism. I can't tell you how to release it but if you are working on the brakes you must know something about your car. Just look it over and see if you can break the code. If I remember the Honda had a pawl on it that I had to hold back as I unscrewed what amounted to an auger that kept a sort of preload on the piston so the parking brake can self adjust. If you are familiar with self adjusters on drum brakes the Honda worked in a somewhat similar manor only it screwed into the piston from directly in line with the direction the piston pushed.

Good luck. And don't break it with the c-clamp, I almost did and it would have cost me many $$$$ to fix it for the customer and the money would have come from my pocket. Email my profile if I can help any further. I'm not sure my answer is all that clear.

Answer 3

Rear Disc Brake Tool

Answer 4

Push in while turning the piston clockwise there are tools that put pressure on the piston while turning notice the two spots on the caliper piston face there the tool pins catch turn and push inward. Your rotor surfaces have been trued with a lathe? If you put new pads on old warped rotor surfaces you did not do a very good brake job. And do you know those shims on the backs of the old pads are there for a reason? Brakes should be worked on by persons with years of experence with braking systems so they operate quietly and stop in the shortest distance.

Answer 5

Did you take the cap off the master cylinder ? It might be full from pushing in the front calipers. If that doesn't work open the bleeder screw slightly on the caliper. The piston may be froze up. Is your brake pad worn more on one end than the other, this is a sign of a non working piston.

Answer 6

Don't use any force to seat it. NO C-clamps.

99.9% of the rear disc brake calipers actually have a screw type piston in them and there's a special tool, you can buy the cube shaped tool, that you use to screw the piston "in" to the caliper housing.

There's always a small indentation in the face of the piston and the tool, cube shaped, has six different sides and one of those sides will fit the face of the pistona nd allow you to turn or twist it back inside with you 3/8" ratchet. The cube has square holes in it to fit your 3/8" ratchet wrench.

Most auto parts stores sell them. even with the right tool it is time consuming.

Good Luck!

Answer 7

i could consider each and every thing Thomas says different than approximately rear discs being a merchandising tactic. There are automobiles that income a great deal from having rear disc brakes. Yours even however isn't one. A motor vehicle as easy as yours won't see any considerable advance in scuffling with skill from including disc to the rear. If something, you would be greater services to dropping the rolling friction interior the rear needed in having the flexibility to stop effectively. in case you have been to pass by way of with this, it would not merely be a count of adjusting out the rear drums for disc. you besides mght ought to alter the grasp cylinder, proportioning valve, and antilock brake module/manifold if it has one. this could be because of the quantity of quantity of fluid had to function the greater desirable pistons in disc brake calipers over what's needed for the smaller pistons in drum brake cylinders. then you definitely besides mght ought to alter your parking brake association. the way a parking brake on drums operates is punctiliously distinctive from a disc brake on the rear. None of that's impossible regardless of if there is even a rear disc version of our motor vehicle which you will scavenge from. whether you will have each and every thing made of scratch, this is all possible. yet realistically it is so lots greater artwork and value than income.

Answer 8

you don't push those in ,you twist them in,if you try to push then in,you,ll probably ruin a caliper,they twist in,and you,ll need a tool to do it with and that can be bought at advance or auto zone either one,good luck with it.
