SOURCE: how do I compress the rear brake piston on 2007

hi from uk most rear brake calipers have auto adjust mechanism and yours may be the same as on uk models whereas to compress the piston back into caliper to facilitate fitting new pads ? you have to both press and rotate piston and this sends piston back on the screw auto adjuster you will notice that piston has a couple of slots on its head ? this is there for enabling screw back having said this there is a rear caliper piston compress tool that does this job and the cheapest tool and good quality is made by draper tools and costs approx £10 in uk but can be obtained at any good auto stores and has instructions on use well worth the investment ? just one tip pistons normally screw back clockwise however! on fiats? the nearside screws anticlockwise so just observe that piston is going back when rotating c/wise if not you can fit a 3/8" drive extension and t bar to the rotator boss and using pressure ?turn piston a/clockwise hope this helps one word of advice !make sure you bleed brakes afterwards to clear out dirty fluid untill clean fluid shows this will improve brake pedal best wishes from uk

SOURCE: what to use to change

You need either a 14, 15, 16, or 17 mm wrench or socket. You just turn the belt tensioner to where it will loosen the belt, And then take the belt off. Do the same thing to get the belt on. It should look like either of these, DEPENDING ON WHAT MOTOR YOU HAVE. dy89302.jpg

    Need engine diogram for 2007 buick lacross 3800 , po128 (ect)


    The code is telling you the engine temp sensor is telling the computer the engine is not warming up as it should.
    Sometimes the problem is the thermostat, or low coolant, and sometimes it is the temp sensor.
    Check the engine temp with an inferred thermometer first.
    Usually the engine temp sensor is a two wire sensor, yellow and black.

    2007 Buick Lacrosse low beam headlights both went out at once. Doesn't appear to be the bulb. Also checked the fuses under the hood and those both appear OK too.


    The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.
