Thumbs up MoT repairs following test fail of my better half's MG ZS.

Fully prepared to replace the "failed" Off Side Outer CV-J Rubber Boot, loosened rear exhaust flange ( corroded bolt ) allowing gas escape ( emissions ) and rear brake pads ( one pad below legal limit). However, asked the Innsworth, Gloucester based one sometimes two-man repair outfit I've used occasionally for over twenty years how much if I supply the parts myself. He quoted a price which I was pleased to accept. The old joints do not like working underneath cars much now and not worth getting my hands dirty for such a good quote. Car ready two hours later.

He's a keen car/bike enthusiast and loves Big Yankee cars... has at least one Cadillac and an ex US-Army 4x4 Truck still in camouflage livery. In the back of his workshop was a real rarity ... A Cotton Motor Cycle. Cottons made in Gloucester and back in the 1970s, I got them to paint and oven bake a stripped, sand blasted motorcycle frame for me. Best of all, the owner of the repair outfit turned up on this superb Blast from the 1961 Past.



Anyone in the Gloucester area needing work on their cars I can thoroughly recommend ... Good prices and fine standard of work from this Automotive enthusiast.... pm for more info.

Thanks for the tip John, no good to me in South Wales but my daughter who lives in Wolverhampton is in Gloucester most weekends visiting her boyfriend. She lived there for a couple of years after finishing uni and it would be great for her and the boyfriend as both know nothing about cars but I will say my daughter does do basics such as oil, water and tyre pressure checks weekly. She normally puts things off until she visits us but this would make more sense.
I have always done mot pre checks on the families cars and never had an advisory so far but this year my health has took a big dip so not sure I will be able to carry out my normal checks.

Usually I enjoy working on the family's cars and my own doing these routine things. However, things crop up when time is not available so getting a job done well professionally at reasonable cost can be very convenient at times. I am tempted to put up details of the Innsworth Based Outfit here but, could be objections to that.

So, meantime I'll pm you with the Outfit's web site link details.

Oh yes, and please get well soon.

Thanks for the link, I will pass it on and hopefully it will help them both out if need arises. As for me I have now been told I have arthritis in knees and ankles which I had already guessed but it's the scan next Tuesday that is more worrying so fingers crossed its not what I am afraid it could be. Fingers crossed and all that.

Thumbs up FREE MoT Re-Test Success.

Arrived a few minutes before the noon re-test appointment and pleased to say the wife's MG ZS passed a little later Just a few routine advisories such as Ball Joint Seals showing signs of wear but not allowing lubricant to escape.

So car we've had from new lives on for another year making it fourteen so far. Good car and still a delight to drive. Love the positive and sharp handling of the MG ZS.

Soon after, I treated the little car to a Hand Car Wash. At one point there were a team of FIVE Romanians working on the car :~

Update with post MoT repair problems.

When I arranged to have some of the MoT "failures" sorted by a repair outfit I've occasionally used for over twenty five years now, the Guvnor mentioned that he sometimes has difficulty with the Handbrake Auto-adjuster on these cars. This was the case with my wife's MG ZS following fitting the new rear Brake Pads I supplied. Drove the car for a few miles the other day and soon after stopping, I placed my hand on both rear wheels. They were very warm. A sure sign of binding brakes.

Jacked the car up and unable to manually rotate the rear wheels with handbrake OFF unless I used a breaker bar on one of the wheels nuts. No chance of spinning the wheel freely as it should with rear pads properly set up with Auto-Adjuster. Both sides were binding so needed fixing.

Because of the way it was parked, started on Driver's side brake binding issue which was the side not as bad as the other side. Soon had the Caliper and the Carrier off after carefully undoing the carrier's two 14mm Bolts. Using wire brushes in my old Black and Decker Electric drill, the various components came up in better condition than expected as these pictures show.

Carrier before wire brush cleaning. :~



After wire brush treatment. Note the Stainless Steel Shims which locate the Pad's Lugs cleaned up well. I will apply some Copper Grease to the slots where the Pads slide into.:~



A smear of Copper Based Grease over the threads and Bolts Interfaces will help assembly and the next time it needs to come apart again :~



Now for the all important priming of the Auto-adjuster to stop them binding :~



This involves cleaning the Caliper's Piston and its Seal with brake fluid. Allow it to soak in the fluid for a few minutes then wipe surplus away with a cloth. They usually clean up nicely with this treatment,Then, using the special socket to rotate the Caliper Piston as in the above image, I first unwind the piston out of the Caliper anti-clockwise a little more than one rotation, then, slowly rotate the Piston back ( clockwise ) both slowly and carefully as far as it will go watching to see the Piston Seal does not get tangled up which sometimes happens if you are heavy handed or wind back too fast. It may be a loose fit over the pads but that looseness will disappear as soon as you start the engine and firmly apply the brake pedal several times. Then check that it can be rotated manually by hand. That I was not able to do prior to this TLC work.

Repeated the process on the other side again with the desired results. Took the car for a three mile run with a numerous light brake applications. No heavy ones at these stage with those virgin new Brake Pads. It is no exaggeration to say that the brakes on this car have always been excellent. Some of the best I've ever used on any ordinary production car. I do not think I'm kidding myself believing they are better now than at anytime since I picked the car up new back in May 2003. Car is a delight to drive.

Hi John
Looking good there mate. I know these rear discs are so prone to a few faults even after fitting new pads etc correctly it's so annoying. Had to change a couple of calipers, had pads jam in carriers, Pistons sieze etc. People have said I haven't serviced them correctly but I know how to do brakes lol.
What puzzles me is the set up is identical on the mk1 and mk2 sterling 825 coupes and Vitesse 827 and I have never encountered any of these problems on any 800 series. I never had pads stick on an angle in carriers, never had a piston sieze or needed to replace a caliper and my Vitesse was 7 years old when I bought it and I used it for 12 years still on original front and rear calipers.
Glad you have it not,d for another year.

Almost certainly problems with MG-Rover Rear Disc Calipers, particularly where Handbrake operation is involved, is invariably due to insufficient care and servicing. Out of sight out of mind scenario. The rear Calipers on my wife's MG ZS were working perfectly as they had always done since day one when we bought it new. The MoT "fail" this time was for the Pad material on one pad being below limits... it looked OK to me but there you go. Having the new Pads I supplied replaced by a pro-outfit saw them binding afterwards. The chap who did the job had reservations about it based on past experience. I dare not tell him he had not primed them properly.... Even very experience folks "in the trade" do not know everything about every car. I specialise in these cars so know some of the ropes as it were.

I'm using a different MoT test station now. They have a special offer of 25 for MoTs which I've used to test four of the family's cars in the past few weeks.

Although it still has five months MoT still to run on the current certificate, the recently acquired MG ZT-T 1.8t I am having check/tested for that 25 special offer ~ not logged on DVLA ~ just a complete MoT check for me to have a pro-assessment of this unknown quantity. Good value for a mere 25.

My friendly MoT tester I've used for twenty five years recently retired used to be of the "they all do that" mindset where Rovers and MGs were concerned. Particularly about handbrake operation. He has not done that for years now and sometimes remarks "They locked out John" ... which in his experience is a surprise and very rare on Rovers. That's because they are rarely given sufficient or even any servicing based on my experience buying used examples from previous owners over the years. Often totally neglected until work needed come MoT time.

and

Out of sight, out of mind.

Wrong on both counts.

Anyway an hour or two leisurely DIYer work by me has the brakes on my wife's car in very good shape indeed now.

Sometimes, some simple TLC to a car's Brakes shows so much improvement it can be like a brake upgrade.
