The front brakes on my suzuki vitara (1998) keep seizing for no apparent reason, checked calipers, pistons, fluid, all good. can anyone help. I.E is there a common problem with the brakes on this model. this problem has just started to happen over last 2 weeks.

It's more than likely one of two things.Either the brake caliper pistons seized and didn't let the brakes release, or you have a wheel bearing seizing up. just check it out ! good-day !

The caliper piston may need to be turned as it is pressed in is the only surprise yuo will have. Good Luck, JROD

Brake fluid from the Master Cylinder leaks if the Master Cylinder is leaking itself otherwise the leak is somewhere else, have some one check this out, it could be anywhere and you should have seen some drops on the floor by now.

Sounds like a "stuck" caliper piston. Many Chrysler products (by example) used "phenolic" pistons in the calipers which were notorious for seizing in the caliper. Replacement pistons are usually made of steel. With the piston seized heat builds up and ruins the seals in the caliper.

You could have a blown master cylinder that is leaking from the back and into the booster area. Take the cylinder loose from the booster and see if there is fluid in that cavity. Sounds like a massive leak. Look at the rubber hoses and metal lines. The reason you cannot pump up the brakes is because the leak is allowing air to re-enter the system so that pressure cannot build up.

I hope helps (remember to rate and comment this).

Going by your description I think it could be something different, I would have the brake master cylinder checked, if you are suffering brake failure and shuddering it sounds like your callipers arent getting equal pressure when you apply the brakes. Or a freat lack of pressure to suffer brake failure. I hope this helps.

the shoes not being adjusted properly or if one shoe has more pad than the other like a primary and secondary them wrong will also create this issue, also brake fluid on drums and shoes.

Most possible reason is a seized piston in the right hand caliper, did you just replace the one side or both?

Be sure you have changed the break oil completely. Otherwise drain the hydraulic system and renew with correct type of oil. If you have a ABS system you have to check that also.

You still have a restriction somewhere on that side if it is the only one that locks up.

You may have contaminated brake fluid. The fluid gets too hot, caused the fluid to expand and lock up your brakes. once it cools it will allow you to move. Flush the brake system, start at the wheel farthest from the master cylinder and bleed the system until all the old dirty fluid is out. Just allow it to gravity bleed, don't waste your time doing the pump and release method. It only gives your buddy a sore foot and if you miscue you **** air back into the line.

Let me know if I can help you with any more info or guidance.

Do you have a brake fluid accumulator(ABS)? If yes, the pistons/pulsing assembly are worn, and may need to be replaced.

If not, you may have a vacuum leak in the power booster (located on the firewall). Check all hose and clamps for a tight fit/cracks,etc. Vacuum leaks cause intermittent brake failure lights.

You may want to park the vehicle on a clean surface, pump the brakes a few times, and check for brake fluid leaks. If there is a leaking wheel cylinder (back brakes) , caliper (front brakes), or brake line, you will be able to see it.

Leaks cause pressure loss, and, thus, the brake warning light will illuminate.
