If you are quick and neat enough about it where you don't drain the whole reservoir, then no. You only need to bleed that line. A trick for bleeding by yourself once your done is to make sure the reservoir is full and the cap is off (don't push the pedal) and open the bleeder on the caliper. Let it gravity bleed drop by drop until no air is present. Top off fluid and check the pedal (with the cap back on)
To bleed brakes on your 2008 Uplander front and rear, disconnect the brake line at the caliper.
No, you do not. If you change the caliper, you will have to bleed that brake line. Have someone press on the brake pedal. Open the bleed valve, while they continue to hold the pedal. Close the valve. Repeat 3 times. We did it 4 times, but 3 should do it. Works great!
It sounds like the rear caliper is frozen up. If it doesn't move you can't bleed it and it won't operate the brakes.
Changing the caliper is an extension to the changing the brakes procedure.The 'extension' is to disconnect the brake line/hose from the caliper.Next extra step is to bleed the brakes - since the new caliper is going to be full of air when you first hook it up.See "Related Questions" below for more extensive coverage of the procedures...
No, as long as your pedal seemed good before the brake job, and you do not loosen the bleeder at all, you do not have to bleed the brakes.
You can take it off the wheel and squeeze it together with a bench wise. You will then need to bleed the air out of all four brakes. To bleed the brakes have someone pump the brake pedal and hold it down while you loosen the bleed valve located on the brake caliper until brake fluid comes out, then retighten the bleed screw and repeat on the other three wheels.
You will need to bleed the brakes, starting from the caliper furthese from the master cylinder then moving closer.
It can be a sticky caliper or you need to change brake pads.
Use a turkey baster to to suction fluid out, or open a bleed fitting on any caliper and pump brakes.
Does this Blazer have four wheel disc Brakes? NEW ANSWER: There's no reason to bleed brakes if you did not open the system.( where brake fluid came out )
There should be no need to bleed the brakes after replacing the rear (or front) brake pads. Make sure you place a rag around the top of the fluid reservoir to catch any excess as you press the pistons back into the caliper body though. If the brake pedal has gone spongy after pad replacement this suggests that the piston seals have failed or the caliper cylinder facess have corroded. On mine the bleed nipples are on the caliper body.
jack up car, support on jack stand, remove wheel, undo 2 bolts behind caliper,undo brake hose, (have someway of blocking hose to keep brake fluid from gravity feeding out. then reverse process with new caliper.(always replace in PAIRS!)bleed brakes,etc..
