Hi Guys sorry for posting this here but I have upmost respect on here for their mechanical knowlege of 300's so a quick question about a Frontera of all things lol Its a 1998 3.2 v6 limited very cheap to carry stuff in, I have a hatchback and so does the other half so might as well get something a bit different to arse about in lol

Car has been for mot and failed, the car had been stood for two and a half years before I got it so I..................

Had the front discs machined flat, also new front pads, got new rear discs and new rear pads and adjusted the handbrake.

MOT fail on rear brake lines corrosion ( now renewed), reflushed through and renewed brake fluid, inc bleeding the load sensing valve.

Mot fail on No rear brakes, wheels could be turned by hand when brake pedal pressed (on rollers).

The fronts didn't do so well at mot time either?

Anybody be able to recommend what next?

The flexi lines are not bulging, the pedal is still spongy and when looking underneath when braking the front calipers are really grabbing on and the rear calipers are doing nothing?

Could an abs light (which is on even thought I have replaced a sensor) could affect any of the above?

I can't think anymore

I have had master cylinder off I dont know if to order a seal kit? as it seems ok, also a replacement load sensing valve?

Ayone able to help:) As I feel like Im banging my head against a wall

Seized Caliper pistons?????????????????/

Seemed ok when I pushed back in when I fitted new discs and pads to rear, but both at once is the puzzler lol

is there a way to bleed the ABS section?

Sounds like a master cylinder problem or possibly the servo. Pump the brake pedal untill it goes stiff. (Make sure the engine isn't on) once stiff, rest your foot on the brake pedal and start the engine, the pedal should drop. If not then you have a servo problem.

Still air in the system m8.Vauxhalls are renown to be awkward to bleed.Get a pipe on the bleed nipple into a jug or bottle with fluid in and gently pump the peddle:)..Takes a short while and keep an eye on the level in the resovior..lee

Stick the rear end up in the air when you bleed. Jack, ramps whatever.

 

Alan..............

Make sure u aint done what I did the other week, if u had the calipers off make sure there back on the right sides.

bleed nipple has to be at the top...

 

I did this by mistake and car would not brake on the rears,

Yep car well in the air and one man bleed kit working very well, I bought a vacumme set off ebay (cheap one) a while ago and used that but its well cheap and crap so I put it back in its box lol, I'm gonna order a master seal seal kit and give that a go, Car pulling pleanty of vac (checked pipe going to servo with pipe off), servo good holds pressure, no bleed on abs unit there's one per wheel and the load sensing valve at the rear. Thinking about getting another load sensing valve but not sure yet.

Its doing my head in how both back brakes have no effort? cheers for the replies :)

Deffo try LSV-known for seizing!

Well Im thinking that but its letting the fluid through to bleed ok enough Im gonna do both then :) as I need to order another part from a 4x4 breakers (I, ahem have max power pedals and ovbiously need to get rid and get some pedal rubbers lol) soon to be in the for sale section :D
