My 1999 infiniti G20 rear calipers have to be twisted clockwise in order to compress them. The auto parts stores have a tool set you can rent that will compress and twist at the same time. I went the cheap route and bought a universal cubed looking tool that attaches to a ratchet and it worked but was really hard to compress and twist at the same time. Definetly recommend the tool set rental.
Should be disc brakes and not adjustable caliper slides to compensate for lining wear unless caliper slides are frozen
Caliper slides frozen? Rear drum brakes? May need to be adjusted
Not the lining themselves. You should lube the caliper and pad slides.
If there are disc brake, it could be frozen caliper slides or a frozen caliper piston. If they are drum brakes, it could be a frozen wheel cylinder.
Sticky/stuck caliper slides, sticky/stuck caliper piston, collapsed brake hose, pinched brake line,
If you don't lube the caliper slide pins and pad slides, they'll bind. You'll get uneven pad wear
On the disc brakes I've seen (not very many), the calipers are self-adjusting. When replacing pads, the caliper must be compressed to accommodate the new, thicker pads. Other than that, I haven't heard of a brake caliper adjustment.Ans 2 - There is no adjustment necessary in Chev/GM front brakes. If they don't work as well as expected. the caliper slides may be very rusty. Scrub the slides with a wire brush then lube with a touch of dry graphite.
I had this same problem with a 91, on mine it was the caliper slides, which allow the brakes to self-adjust.I was able free them up with penatrating oil and then work them back and forth until they worked on their own.The slides are where the mounting bolts go through the calipers. Hope this helps Good Luck.
Disc brakes are supposed to drag on the rotors, if you think they are too tight you will have to replace the calipers. The caliper slides may need cleaning and new hardware to allow the calipers to move freely.
If you have drum brakes make sure they are adjusted properly. Adjust so they are just locked and then back off adjuster 5 notches. If you have disc brakes, make sure that caliper slides are not frozen
I don't know exactly how to do it on that particular car without looking at it, but in general disc brakes are all pretty much the same. Just remove the two bolts holding the calipar to steering nuckle, its probably an Alan in that car. take the caliper off, it may be tight. Use a C-clamp and one of the old pads and compress the cylinder of the caliper all the way back. It should be tight, but not really tight. If you have a lot of trouble getting it to compress, then the caliper is no good. lube all the slides for the bolts, I think there are 2 little cylinders that go around the two main bolts. clean them and lube them before putting the caliper back on. replace the brake pads and put the caliper back on and put the bolts back and tighten. When you compress the cylinder in the caliper, brake fluid may start coming out of the master cylinder. Don't worry, your just pushing all the fluid back up, and if there is too much in there, it comes out the top of the master cylinder, but this doesn't hurt anything.
hope this helps....you will most likely need a 7mm Alan wrench....remove the 2 slides and pull the caliper off. the pads should pop right out. then compress the piston on the caliper using a compression tool or a c-clamp would work. replace with your new pads and make sure to use caliper lube on your contact points (anywhere the pads touch the caliper) on the drivers side do the same but you will need a small flat head screw driver to disconnect the sensor. put the sensor pad on the inside and put your caliper bace on. pump your brake pedal about 5 times without the car started or un till you have a good pedal.......good luck
